1. Carbon steel
Carbon steel is a very common metal composite material, widely used in various places in daily life.
Laser Welding Machine can achieve welding, and the actual effect is better. The residue content determines the quality of spot welding.
To ensure the quality of laser welding, heating is required when the carbon content exceeds 0.25%. When welding steels with different carbon contents, the gas welding gun can be slightly offset to the side of the low-carbon environmentally friendly material to ensure the quality of the joint.
Because the heating and cooling rates during Water-cooled
Handheld Laser Welder welding are very fast, when welding carbon steel, the sensitivity of welding cracks and vacancies will increase with the increase of carbon content.
Steel with medium and high carbon steel content and ordinary carbon steel can achieve good laser welding, but heating and post-welding treatment processes are required to eliminate internal stress and prevent cracks.
2. Stainless steel plate
Stainless steel welding is easier to obtain high-quality joints than basic welding. Laser welding machine manufacturers believe that due to the high welding efficiency and small heat damage zone of laser welding.
It alleviates the adverse effects of overheating and large thermal expansion coefficient during stainless steel welding, and the welding has no defects such as pores and impurities.
Compared with carbon steel, stainless steel is easier to have deep melting and narrow welding due to its low thermal conductivity, high laser energy absorption rate and high melting efficiency.
Using small centrifugal fan laser welding to weld metal sheets can obtain joints with good appearance, smooth and beautiful welding.
