What materials can handheld laser welding machine weld

Updatetime: 2022-12-28 09:30View:
Laser welding is an efficient and precise welding method using high -energy density laser beam as a heat source. In the thin plate welding industry, the handheld laser welding machine has become a favorite industry technology for the market with the advantages of easy operate, high efficiency, and flat welds.
The laser welding machine welding thermal affects the area small, the material is deformed, and no subsequent processes are required. Laser beams are easy to guide and focus to achieve transformations in all directions. Laser welding has high production efficiency, stable and reliable processing quality, and good economic and social benefits.
Laser welding system is an advanced welding process. The welds are deep and narrow, and the welds are bright and beautiful. The minimum hot input. Due to the high power density, the melting process is extremely fast, the input workpiece heat is very low, the welding speed is fast, the thermal deformation is small. During the generation of welds, the melting pond is constantly stirred, and the gas is easy to come out, resulting in generating pore -free welded welds. The high cooling speed after welding can easily make the weld tissue slightly detailed, and the intensity, toughness and comprehensive performance of the weld are high.

Due to the small spot focus of the fiber laser welding machine, the welding seam can be located high -precision, and the beam is easy to transmit and control. It does not need to replace the welding torch and nozzle frequently, which significantly reduces the aid time of the shutdown. Because the energy comes from laser, the workpiece has no physical contact, so it has no power to apply for workpieces. In addition, magnetic and air have no effect on laser. Due to the low average thermal input and high processing accuracy, the processing cost can be reduced. In addition, the laser welding cost is low, which can reduce the cost of workpiece. It is easy to achieve automation, and effectively controls the strength and fine positioning of the beam.
Laser welding metal is one of the important aspects of laser material processing technology. Many factories now have welding demand, but the technology is still used in the old traditional welding method. After using the laser welding system, the labor cost, work efficiency and product quality of many enterprises have been greatly improved, so it has been recognized by many factories.
Faced with the emergence of new products, many companies currently have a wait -and -see attitude and do not know whether they can meet their own needs. Today, let's talk about which materials can the fiber laser welding machine be welded?
1. Stainless steel
The thermal expansion coefficient of stainless steel is high. When welding, it is prone to overheating. When the heat -impact area is slightly larger, it will cause serious deformation problems. In addition, the relatively low thermal conductivity coefficients, high energy absorption and melting efficiency of stainless steel have a good, smooth and beautiful welding joint after welding.

2. Carbon steel
Ordinary carbon steel can be welded directly using handheld laser welding machine. The effect is comparable to stainless steel welding, and the heat affects the area smaller. Preheating, insulation after welding to eliminate stress and avoid cracks.
3 Mold steel
Handheld laser welding machines are suitable for various types of mold steel welding, and the welding effect is very good.
4. Aluminum and aluminum alloy
Aluminum and aluminum alloys are high reflected materials. In the welding pond or root may occur during the molten pond. Compared with the previous several metal materials, aluminum and aluminum alloy requirements will be higher. However, as long as the selected laser welding parameters are appropriate You can get welding seams that are equivalent to the mechanical properties of the mother material.
5. Copper and copper alloy
The thermal conductivity of copper is very strong. It is easy to produce unproof and partial melting during welding. Usually, the copper material is heated during welding to assist the welding. Here I am talking about copper thin materials. Direct welding, because of its energy concentration, fast welding speed, and the high heat -vitality of copper has a small impact on it.
6. Welding between heterogeneous materials
Hand -holding laser welding machines can be performed between a variety of alien metals, such as copper -nickel, nickel -titanium -titanium, copper -titanium -titanium -molybdenum -copper -copper, low -carbon steel -copper, etc. Laser welding can be performed under conditions (gas or temperature).
Welding between heterogeneous materials
Most friends who have not been exposed to laser welding system will think that only stainless steel can be welded, but laser welding machine applications are very extensive compared to other welding equipment. The applicable materials include carbon steel, mold steel, alloy steel, stainless steel, titanium, nickel, tin, copper, aluminum, chromium, gold, silver and other metals and its alloys.
Laser welding machine is widely used in the common welding materials such as the kitchen and bathroom industry, home appliance industry, advertising industry, mold industry, stainless steel products industry, stainless steel engineering industry, doors and windows industries, craft industry, home products industry, furniture industry, automotive accessories industry and other common welding materials.
