Laser Welding Machine For Sale

In the field of partial metal sheet welding, the laser welding machine has become a new type of industrial technology favored by the sales market with its advantages of easy entry, high efficiency, and flat and beautiful welding. More and more customers are willing to understand and use hand-held laser welding machines, so which materials can laser welding machines be welded?

1. Stainless steel

Due to its large linear expansion coefficient, stainless steel is prone to thermal deformation during traditional welding. The laser welding heat-affected zone is very small, which basically solves this undesirable phenomenon. And because stainless steel has low thermal conductivity, high energy absorption rate and melting efficiency, it is easier to obtain well-shaped, smooth and beautiful deep penetration narrow welds.

2. Carbon steel

The quality of its welding depends on the content of impurities. As the carbon content increases, the susceptibility to weld cracks and notches will increase. Therefore, medium and high carbon steel and ordinary alloy steel should be preheated before welding to eliminate stress and avoid cracks. In this regard, cold welding machines are more suitable, because it has less heat than laser welding, and the temperature of the molten pool is also much lower.

3. Aluminum and aluminum alloy

Compared with the first few metal materials, aluminum and aluminum alloys have higher requirements for parameters, but as long as the selected welding parameters are appropriate, a weld with mechanical properties equivalent to the base metal can be obtained.

4. Copper and copper alloys

The thermal conductivity of copper is very strong, and it is easy to produce incomplete penetration and partial non-fusion during welding. Usually, the copper material is heated during the welding process to assist the welding, but for thin copper, the laser is easy to penetrate and penetrate the weld. , The high thermal conductivity of copper has little effect on it.

5. Welding of different materials

Because the laser welding machine is a high-heat laser beam for instant welding, it can also weld different materials. Between various metal materials such as copper-stainless steel, copper-aluminum, copper-carbon steel, copper-red copper, copper-nickel, nickel-titanium, copper-titanium, titanium-molybdenum, etc., under certain standards (steam (Body or temperature) can carry out laser welding.
