Available Sheet Metal Welding Process
HSJ sheet metal welding comes with various types of sheet metal welding, including gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), and resistance welding.

Typical types of sheet metal welding processes including, MIG welding, TIG welding, resistance welding, projection welding, robotic MIG and TIG welding, and laser welding on various metallic and aluminum alloy surfaces as well as on stainless steel and iron.

MIG welding
MIG welding, also called MAG welding, is a continuous wire welding process where a shielding gas ensures firing bath protection. MIG or MAG welding is used where high productivity and high flexibility of use are required. While MIG welding requires the use of inert gas, MAG welding is carried out through an active gas. MIG welding can be also performed on thin metal, such as thin steel or aluminum.

TIG welding
TIG welding is one of the most popular welding methods since it provides high-quality components. Especially indicated to weld thin parts, it can be used for both continuous and spot welding.

Resistance welding
Resistance welding is a metal fusion welding technique where the material is heated by electrical resistance. Generally used to weld iron and steel, resistance welding guarantees high-quality standards on welded components while ensuring time and cost savings. If you want to learn more about resistance welding, we will explain everything to you.

Projection welding
Projection welding requires studs to be placed on the metals to be welded. During the metal welding process, the welding current is focused on the stud that heats to obtain complex welds, with final results that ensure excellent quality at low costs. Basically, projection welding is a type of resistance welding that uses projection.

Robotic TIG MIG MAG welding
Robotic welding is performed by programmable industrial robots. Mainly used in situations that require repeated welding, it guarantees repeated precision which is hard to achieve with manual welding. Greater precision and higher productivity are the main advantages of robotic welding.

Laser welding
Laser welding allows metals and metallic alloys to be welded, creating a thin and deep weld, with reduced heat deformations thanks to the reduced heat, even on materials that could not otherwise be welded. Precision, cleanness, minimal heat input, and fast manufacturing are just a few of the advantages of laser welding.

Laser Cutting Galvanized Steel Sheet Technology(2024年01月29日)

https://www.hsjfabrication.com/laser-cutting-galvanized-steel-sheet-technology.html

Nowadays, it is common for sheet metal companies to use laser cutting. The advantage of sheet metal laser cutting is that it is a processing method that does not touch the material, so it will not damage the surface of the sheet, and there will be no burrs on the cut surface, which is a processing method that can significantly reduce the subsequent processes. However, laser cutting will also encounter various practical problems that are difficult to overcome. Here we will focus on the cutting difficulties and solutions of laser cutting galvanized steel, which are commonly used in daily processing.

According to auxiliary gas, there are generally three laser cutting processes for galvanized steel, namely air cutting, oxygen cutting, and nitrogen cutting. Now, let's analyze the advantages and disadvantages of the three cutting processes:

1. Cutting with air
The advantage is that the processing cost is meager, and only the electricity costs of the laser itself and the air compressor need to be considered, and there is no need to generate high auxiliary gas costs. It is an economical and efficient cutting method. But the shortcomings on the cut surface are equally obvious. First of all, the air-cut section will produce bottom burrs, and the products after laser processing must undergo secondary processing such as deburring, which is not conducive to the entire production process. Secondly, the section of air cutting is easy to turn black, which affects the quality of the product. Therefore, the advantages of laser processing without subsequent processing can not be reflected, so in laser cutting galvanized steel, many companies are unwilling to choose this method.

2. Cutting with oxygen
It is the most traditional and standard cutting method. The advantage is that the gas cost is low, and in the sheet metal processing dominated by carbon steel, there is no need to frequently switch the auxiliary gas, which is convenient for factory management. But the disadvantage is that after oxygen cutting, there will be a layer of oxide scale on the surface of the cut surface. If the product with an oxide scale is directly welded, the oxide scale will naturally peel off over time. This is one of the reasons why galvanized sheet welding is easy to weld.

3. Cutting with nitrogen
When nitrogen is used for high-speed processing, the role of nitrogen is different from oxygen used for combustion, but it plays a protective role, so the cut section will not produce an oxide scale. Many companies are fancy it, so the cutting of galvanized steel sheets often use nitrogen for processing.

Bending metal sheet at home is a forming process. In process of custom sheet metal bending, a metal sheet is passed through a pressure device and a special mold to transform a desired three-dimensional shape by applying bending stress. We are professional sheet metal bending supplier and we provide custom sheet metal bending services.

What is Sheet Metal Bending?
The process of precision sheet metal bending involves transforming a flat sheet of metal into a V-shaped opening. To achieve this, the workpiece is positioned onto a concave die that has a V-shaped opening. Subsequently, a wedge-shaped tool (knife) applies pressure to the workpiece, pushing it into the V-shaped opening and bending the plate to the desired angle.

HSJ Sheet Metal Bending Process
The bending, or press brake forming or folding, is a forming process in which the plastic deformation happens over an axis. Bending does not normally change the thickness of the sheet metal.

Punches and dies press brakes are used to perform this process. A die can be a lower V- or U-shaped tool. The plate is pressed into the die to made a bending part.

The CNC controls of our machines will precisely regulate the lowering depth and helps to maintain the minimum bending radius.

HSJ Custom Sheet Metal Bending Servies
HSJ offers professional Custom Sheet Metal Bending Services with seven different methods available:

V-bending - this method involves using a v-shaped die and punch to bend sheet metal to achieve acute, obtuse, or 90° bend angles.

Air Bending - leaves space (or air) underneath the sheet, allowing for more bend angle control than conventional v-bending, resulting in higher accuracy due to less springback.

Bottom bending - this method requires a higher tonnage press to achieve precise bend angle control.

Wipe Bending - involves holding the sheet metal against a wipe die via a pressure pad, and using a punch to force the edge of the sheet beyond the die and pressure pad, causing it to bend.

Roll Bending - uses sets of rollers to feed (and bend) the metal stock into rolls, tubes, cones, or curved shapes.

Rotary Draw Bending - the sheet metal is clamped to a rotating die and drawn around the die to form a geometry that matches the desired bend radius, with an internal supporting mandrel to prevent wrinkling on the surface and minimize the risk of scratches.

Customized Shape Bending - HSJ accepts custom one-piece molding requests for high-efficiency production.

How to Control Sheet Metal Bending Tolerances?

In the process of precision metal bending, tolerances are inevitable. Sheet metal bending tolerances within a certain range are allowed.

Our sheet metal bending tolerances are less than 5.0 for sheets of ±0.1 and 5.0 or more for ±0.3. And those over the range should be caused by improper operation. What we need to do is to control the sheet metal bending tolerances to the smallest possible range.

Therefore, when cutting the material, it is necessary to ensure that the sheet metal bending tolerances of the plate shearer can be controlled. In addition, shear plates and CNC machining also play a significant role in sheet metal processing.

Material:

Aluminum sheet（SUS/ LOW STEEL/IRON/ OTHER STEEL）

We offer OEM/ODM services.

We have professional designer team provide the professional service from drawing to product finished.

Laser cutting technology including iron laser cutting, metal plate laser cutting and steel profile cutting is widely used in the processing of metal and non-metal materials, which can greatly reduce the processing time, reduce the processing cost and improve the quality of the parts.

Laser cutting is realized by high power density energy generated by laser focusing. And controlled by computer, through the pulse laser discharge, thus the output controlled repeated high frequency pulse laser, the formation of a certain frequency, pulse width of the beam, the pulse laser beam through the light path transmission and reflection and through the focusing lens group focused on the machining surface, forming a subtle, high energy density, intensity, focal spot near to processing surface, with instantaneous high temperature melting or gasification materials processed. Each high-energy laser pulse splashes out a tiny hole on the surface of the object in an instant. Under the control of a computer, the laser processing head and the processed material move in a continuous relative motion according to the pre-drawn pattern, so as to process the object into the desired shape. During cutting, a coaxial airflow with the beam is ejected from the cutting head to blow out the melted or vaporized material from the bottom of the cut (note: if the blown gas and the cut material produce thermal effect reaction, this reaction will provide additional energy needed for cutting; The airflow also cools the cut surface, reduces the heat affected zone, and keeps the focusing lens free of contamination. Compared with the traditional plate processing method, laser cutting has the advantages of high cutting quality (narrow incision width, small thermal impact zone, smooth incision), high cutting speed, high flexibility (can cut any shape at will), wide material adaptability and so on.

We have steel laser cutter for sale and we provide the high-quality steel laser cutting service.

1. Power density
Power density is one of the most critical parameters in laser processing. With a higher power density, the surface layer can be heated to the boiling point within a microsecond time range, resulting in a large amount of vaporization. Therefore, high power density is beneficial for material removal processing, such as drilling, cutting, and engraving. For lower power densities, it takes several milliseconds for the surface temperature to reach the boiling point. Before the surface layer vaporizes, the bottom layer reaches the melting point, and it is easy to form a good fusion weld. Therefore, in conductive laser welding, the power density ranges from 10 ^ 4 to 10 ^ 6W / CM ^ 2.

2. Laser pulse waveform
Laser pulse waveform is an important issue in laser welding sheet metal, especially for sheet welding. When the high-intensity laser beam hits the surface of the material, 60 ~ 98% of the laser energy will be reflected and lost on the metal surface, and the reflectivity changes with the surface temperature. During a laser pulse, the reflectivity of the metal varies greatly.

3. Laser pulse width
Pulse width is one of the important parameters of pulse laser welding sheet metal. It is not only an important parameter different from material removal and material melting, but also a key parameter that determines the cost and volume of processing equipment.

Metal fabrication are important in creating products and structures. Among various sheet metal components manufacturers, HSJ china sheet metal stamping company can be a good choice for you!

Laser welding sheet metal is an efficient and precise welding method that uses a high-energy density laser beam as a heat source. Laser welding is one of the important aspects in application of laser material processing technology. In 1970s, it was mainly used for welding thin-wall materials and low-speed welding. The welding process belongs to the heat conduction type, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses to the inside through thermal conduction. By controlling the laser pulse width, energy, peak power and repetition frequency and other parameters, the workpiece is melted to form a specific molten pool. Due to its unique advantages, it has been successfully applied to the precision welding of micro and small parts.

The effect of defocusing on welding quality

Laser welding sheet metal usually requires a certain amount of defocus, because the power density at the center of the spot at the laser focal point is too high, which will easily evaporates into holes. On each plane away from the laser focus, the power density distribution is relatively uniform.

There are two ways to defocus: positive defocus and negative defocus. The focal plane above the workpiece is positive defocus, otherwise it is negative defocus. According to the theory of geometric optics, when the distance between the positive and negative defocusing planes and the welding plane is equal, the power density on the corresponding plane is approximately the same, but in fact the shape of the molten pool obtained is different. In the case of negative defocusing, a larger penetration depth can be obtained, which is related to the formation process of the molten pool. Laser heating 50 ~ 200us material begins to melt, forming liquid metal and partial vaporization, thus forming high-pressure steam, and spraying at a very high speed and emitting dazzling white light. At the same time, the high-concentration vapor moves the liquid metal to the edge of the molten pool, forming a depression in the center of the molten pool. In the case of negative defocus, the internal power density of the material is higher than the surface, and it is easy to form stronger melting and vaporization, so that the light energy is transmitted to the depth of the material. Therefore, in practical applications, when the penetration depth is large, negative defocusing is used; when welding thin materials, positive defocusing should be used.

Bending Technology(2021年)

Metal fabrication are important in creating products and structures. Among various sheet metal components manufacturers, HSJ china sheet metal stamping company can be a good choice for you!

Sheet metal bending processing and forming are carried out on the plate bending machine. Place the workpiece to be formed on the bending machine, lift the brake shoe with the lifting lever, slide the workpiece to the appropriate position, then lower the brake shoe to the workpiece to be formed, and apply force to the bending lever on the plate bending machine to achieve metal bending. The minimum bending radius is a function of the ductility and thickness of the shaped metal. For aluminum plates, the bending radius of the metal is greater than the thickness of the plate. When bending, due to a certain rebound, the metal bending angle is slightly larger than the required angle. The bending of sheet metal is carried out in a metal processing workshop.

Bending technology

1. After the sheet metal bending process, the two sides of the corner will protrude from the metal due to the extrusion, resulting in a larger width than the original size. The protrusion size is related to the thickness of the material used. The thicker the material, the greater the protruding point. To avoid this phenomenon, you can make a semicircle on both sides of the bending line beforehand. The diameter of the semicircle is preferably more than 1.5 times the thickness of the material. The same method can be used for the reversal design of the side material.

2. When bending sheet metal, the internal R angle is preferably greater than or equal to 1/2 of the material thickness. If you do not make the R angle, the right angle will gradually disappear after multiple punching and the R angle will naturally form. After this, the length of one or both sides of this R corner will be slightly longer.

3. The sheet metal is easily deformed after being accepted. In order to avoid the occurrence of deformation, an appropriate amount of reinforcement aid at a 45-degree angle can be added at the bend to increase its strength on the principle of not interfering with other parts.

Sheet Metal Bending Process(2021年)

As a professional stainless steel fabrication factory and sheet metal fabrication factory, Shenzhen HSJ Metal Fabrication Co., Ltd. has rich experience in providing professional sheet metal fabrication products to customers! With up-to-date technology and high-end sheet metal fabrication machines, we dedicated to provide high-quality custom sheet metal parts.

Under the pressure of the upper or lower model of the bending machine, the sheet metal bending process first undergoes elastic deformation and then enters plastic deformation. At the beginning of plastic bending, the sheet is free to bend. As the upper model or the lower model exerts pressure on the sheet material, the sheet material and the inner surface of the V-shaped groove of the lower die gradually come close to each other. At the same time, the radius of curvature and the bending force arm gradually become smaller, and the pressurization continues until the end of the stroke, so that the upper and lower models are in full contact with the plate at three points. At this point, a V-shaped bend is completed, which is what we commonly call a bend.

Sheet metal box bending technology is constantly improving. Especially in the application of some precision stainless steel bending, secc sheet metal decorative parts bending, laser welding sheet metal bending, aircraft parts bending, copper plate bending, etc., it further puts forward higher requirements on the surface quality of the shaped workpiece. The traditional bending process is easy to cause damage to the surface of the workpiece, and the surface in contact with the mold will form an obvious indentation or scratch. This will affect the aesthetics of the final product and reduce the value judgment of users on the product.

Basic Knowledge of Manual Laser Welding(2021年05月13日)

hsjfabrication — 2021-05-07T18:33:57+0900

https://www.hsjfabrication.com/products/laser-welding-fabrication.html

1. What is laser welding?

Laser welding is a common welding technique in which the laser output from the laser is transmitted into the optical fiber through the coupling system, and then focused on the workpiece through the laser output system. Laser welding can be divided into manual laser welding and automatic laser welding according to the operation mode.

2. Specific application of manual laser welding

Today, most manual laser welding equipment uses fiber lasers. The laser achieves long-distance output through optical fiber, so it is more popular with users in terms of beam quality, light spot, energy loss and welding freedom. The equipment is streamlined, flexible to use, and the price is cheap. The focus is on the point where the welding function and process quality are better than the hard light path. The welding machine is more powerful, and some manual fiber laser welding machines adopt the new technology of swinging the laser welding head to realize the adjustment of various parameters such as the light spot, so the user does not need to worry that the distance between the workpieces is a little too large and the welding will be affected ( the welding can be achieved between general distance of 3-5MM). Therefore, manual laser welding can significantly improve the application function and scope of welding and reduce the difficulty of welding.

In addition, because the handheld fiber laser welding machine adopts fiber laser, it is easy to maintain, even without maintenance. As long as it is cleaned daily, there is no loss of consumables. Therefore, it is widely used in welding materials such as metal and thin plates, which solves the problem of cabinets, kitchens, toilets, stairs and elevators. A series of complicated and irregular welding process problems in industries such as, shelves, ovens, stainless steel doors and windows guardrails, distribution boxes, and stainless steel home furnishings.

Of course, manual laser welding is not a panacea. When operating different workpieces, you still need to refer to different requirements for selection.

Analysis on the Advantages and Disadvantages of Laser Welding(2021年05月12日)

hsjfabrication — 2021-05-07T18:32:20+0900

https://www.hsjfabrication.com/products/laser-welding-fabrication.html

1. What is laser welding?

Laser welding is an efficient and precise welding method that uses a high-energy density laser beam as a heat source. It is one of the important aspects of the application of laser material processing technology. Generally, continuous laser beams are used to complete the connection of materials. The metallurgical physical process is very similar to electron beam welding, that is, the energy conversion mechanism is completed through a "key-hole" structure. The equilibrium temperature in the cavity reaches about 2500 ℃, and the heat is transferred from the outer wall of the high temperature cavity to melt the metal surrounding the cavity. The small hole is filled with high-temperature steam generated by the continuous evaporation of the wall material under the irradiation of the light beam. The light beam continuously enters the small hole, and the material outside the small hole flows continuously. As the light beam moves, the small hole is always in a stable state of flow. The molten metal fills the void left by the small hole and condenses with it, and the weld is formed.

2. Advantages of laser welding

(1) Fast speed, large depth and small deformation.

(2) It can be welded at room temperature or under special conditions, and the welding equipment is simple. For example, when the laser passes through an electromagnetic field, the beam will not shift; the laser can be welded in vacuum, air and certain gas environments, and can be welded through glass or materials that are transparent to the beam.

(3) Laser welding can weld refractory materials such as titanium and quartz, and can weld heterogeneous materials with good results.

(4) After the laser is focused, the power density is high. When welding high-power devices, the aspect ratio can reach 5:1, and the highest can reach 10:1.

(5) Micro welding is possible. The laser beam can obtain a small spot after being focused, and can be accurately positioned with precision laser welding, which can be used in the assembly welding of micro and small workpieces that are automatically produced in large quantities.

3. Disadvantages of laser welding

(1) The assembly precision of the weldment is required to be high, and the position of the beam on the workpiece must not be significantly shifted. This is because after the laser is focused, the spot size is small and the weld is narrow, which is filled with metal materials. If the assembly accuracy of the workpiece or the positioning accuracy of the beam does not meet the requirements, it is easy to cause welding defects.

(2) The cost of lasers and related systems is relatively high, and the one-time investment is relatively large.

Eight Common Problems of Sheet Metal Press Parts(2021年05月11日)

hsjfabrication — 2021-05-07T18:31:44+0900

https://www.hsjfabrication.com/sheet-metal-stampings/

1. The characteristics of sheet metal press parts

Sheet metal press parts have the characteristics of light weight, high strength, electrical conductivity (can be used for electromagnetic shielding), low cost, and good mass production performance. They are widely used in the fields of electronics, communications, automotive industry, and medical equipment. For example, in computer cases, mobile phones, and MP3, sheet metal parts are an indispensable part.

2. Eight common problems in the production of sheet metal press parts

(1) Burr: In the process of punching or trimming the edges and corners, the remaining material is not completely left, and the burr is generated at the lower part of the cut surface of the steel plate. When the height of the burr is above 0.2mm, the iron powder will damage the mold and produce covex or concave.

(2) Concave and convex: The surface of the material is abnormally convex or concave, which is caused by foreign matter (iron filings, dust) in the unwinding line.

(3) Roller printing: it is caused by foreign matter attached to the cleaning roller or the feeding roller (occurred at a fixed pitch). Under normal circumstances, the foreign matter of the roller printing on the sheet can be removed.

(4) Sliding mark: It is caused by the sliding of the roller and occurs when it stops or accelerates suddenly.

(5) The crushing of the coil material may cause the edge of the sheet metal press parts to wrinkle: the guide roller of the uncoiling line may be caused by the small guide roller gap on the mold, which is caused by the unbalanced feeding of the coil.

(6) Scratches: The main reason for the scratches on the sheet metal press parts is due to sharp scars on the mold or metal dust falling into the mold. The preventive measures are mainly grinding the scars on the mold and removing the metal dust.

(7) Bottom cracking: The main reason for the bottom cracking of sheet metal press parts is poor plasticity of the material or excessive pressing of the die holder. Preventive measures can be to replace materials with better plasticity or loosen the holder.

(8) Wrinkles on the side wall: The main reason for the wrinkles on the side wall of the sheet metal press parts is that the thickness of the material is not enough (the smaller the allowable thickness is thin) or the upper and lower molds are installed eccentrically, resulting in a large gap on one side and a small gap on the other. The preventive measures are immediate replacement of materials and readjustment of molds.

Application of Precision Laser Welding in Industrial Iron Sheet(2021年05月10日)

hsjfabrication — 2021-05-07T18:30:26+0900

https://www.hsjfabrication.com/products/laser-welding-fabrication.html

1. What is precision laser welding?

Precision laser welding is a new type of welding method that uses laser beams as energy sources to impinge on the welded joints to achieve the purpose of welding. It has the characteristics of good welding performance and small deformation, and is widely used for processing and welding on a variety of metals, such as stainless steel plates. So can the precision laser welding machine weld iron sheets?

The answer is yes. With the current industrial development, the application of iron sheets in the industrial field is becoming more and more extensive, and welding as a connection method of iron sheets requires very high skill control. Because of the characteristics of thin iron sheet, high melting point, and simple weld penetration, traditional welding methods often cause weld penetration and excessive defective products when welding iron sheets.

2. Advantages of precision laser welding in industrial iron sheet processing

(1) The welding speed is relatively fast, and the welding seam is smooth and beautiful;

(2) The heat-affected zone is small, the deformation is small, and no treatment or simple treatment is required after welding;

(3) The precision laser welding machine controls the laser beam through an industrial computer to perform non-contact processing on the product, which can weld some places that are difficult to weld with traditional welding equipment;

(4) The laser welding method will not weld through the product. There are many good products, high positioning accuracy, and easy to realize automation.

3. Calculation of relevant parameters for precision laser welding

Laser peak power calculation: the instantaneous power of the laser when it actually emits light. The laser peak power is equal to the uniform power divided by the duty cycle. It is generally on the order of several kilowatts.

Laser pulse energy calculation: refers to the output energy of a single pulse. Determined by the capacity, voltage and xenon lamp of the energy storage capacitor. This is an important indicator of precision laser welding. When spot welding, the stability of single point energy has a great influence on the quality of laser welding.

1. Welding is made according to the requirements of drawings, technology, and processes. If the drawings are incorrect, the welding of the workpieces is wrong, and the welding and re-cutting are required. Then the piece is processed as defective products.
2. When welding sheet metal, beveling is required in some places. When the processed part has no groove, or when welding the profile, the groove should be polished according to the situation. If the groove needs to be processed, it should be processed and the problem should be reported to the department head.
3. When welding, the shape and position tolerance of the workpiece should be guaranteed, and the shape and position tolerance of the non-machined surface should be implemented according to IT15 level.
4. In the case of welding material replacement, if the thickness of the sheet material does not meet the requirements of the drawing, it cannot be replaced without the written consent of the technical department.
5. The welding seam in sheet metal welding is strictly in accordance with the drawings. When continuous welding is necessary, it must be continuous welding. When intermittent welding is necessary, it must be intermittently weld. If there is no required intermittent welding length and length as shown in the drawing, the standard welding is 8 ~ 10mm at every 50mm interval, and the distance of each welding point must be uniform.
6. Continuous welding seams are required to be straight and smooth, without obvious unevenness, welding penetration, welding deviation, welding scar, porosity, undercut and other phenomena. The welding angle of the weld is subject to the drawings. If there is no requirement, ensure that the welding corner is the minimum thickness of adjacent parts.
7. After welding, each weld should be polished. Remove welding slag and peripheral burrs.
8. Parts that require bending in the drawings cannot be welded without the written consent of the technical department.
9. During the welding of sheet metal parts, the parts that need to be struck can be lightly hammered to the required size with a small manual hammer, and it is not allowed to be struck with an iron hammer on the flat of the sheet metal.

Many people know that laser cutting machines can be used to cut metal parts, and the laser cutting of metal parts is very precise. Because when this kind of mechanical equipment and laser cooperate, the effect will be very good. But what many people don't know is that it can be used not only to cut metal parts, but also to cut plastic parts, or parts made of other materials.

Many factories now use metal cutting laser cutter. If there is no such equipment, the production of the factory will be in a state of stagnation, because laser cutting is more accurate and faster than manually cutting some parts, it can emit high-density laser beams in a short time. The temperature of these laser beams is very high, so metal parts will vaporize in an instant, so accurate cutting can be performed. This cutting machine is equipped with computer programming, so there will be no difference in the cutting process.

In fact, the laser cutting machine is not only used for metal materials, it can also be used for cutting other materials, for example, for cutting plastic materials, it can also cut accurately, and the speed is very fast, so it is a giant of industrial society in the machinery and equipment, because it works fast and does not limit the material. In addition, it can cut a variety of materials, and the cutting precision is very high, so now many factories will purchase this equipment, and wmany of the internal parts of many household appliances we buy are cut out by this cutting machine.

https://www.hsjfabrication.com/products/custom-laser-welded-parts.html

Laser welding sheet metal can be achieved using continuous or pulsed laser beams. The principle of laser welding can be divided into heat conduction welding and laser deep welding. Power density less than 104 ~ 105W /c㎡ is heat conduction welding. At this time, the penetration is shallow and the welding speed is slow. When the power density is greater than 105 ~ 107W / c㎡, the metal surface is recessed into "holes" under the action of heat, forming deep penetration welding, which has the characteristics of fast welding speed and large aspect ratio.

The effect of defocusing on welding quality

Welding speed

The welding speed will affect the heat input in per unit time. If the welding speed is too slow, the heat input is too large, causing the workpiece to burn through. If the welding speed is too fast, the amount of heat input is too small, resulting in impervious welding of the workpiece.

Bending technology

4. It is not easy to maintain the straightness of the general sheet metal parts when they are long and narrow, and it is easier to deform after being stressed. Therefore, we can fold an L shape or fold two sides into a ㄇ shape to maintain its strength and straightness, but often the L and ㄇ shape cannot be connected from beginning to end. What should we do when it is interrupted due to certain factors? At this time we can hit the right amount of ribs to increase its strength.

Sheet metal processing technology is constantly improving. Especially in the application of some precision stainless steel mental bending, stainless steel decorative parts bending, aluminum alloy bending, aircraft parts bending, copper plate bending, etc., it further puts forward higher requirements on the surface quality of the shaped workpiece. The traditional bending process is easy to cause damage to the surface of the workpiece, and the surface in contact with the mold will form an obvious indentation or scratch. This will affect the aesthetics of the final product and reduce the value judgment of users on the product.
