Laser welding of steel materials is a very well-known process for laser welding companies. As a manufacturer of laser welding fume filters, Pure-Air is well-known in the industry for its high quality, energy saving and environmental protection.

1. For carbon steel laser welding and ordinary alloy steel laser welding, carbon steel laser welding generally has a good effect, and its welding quality depends on the content of impurities. Just like other welding processes, sulfur and phosphorus are sensitive factors for welding cracks. In order to achieve the best laser welding effect, preheating is required when the carbon content exceeds 0.25%. When steels with different carbon content are welded to each other, the welding torch can be slightly tilted to the side of low-carbon materials to ensure the quality of the joint. Low carbon rimmed steel is not suitable for laser welding due to its high content of sulfur and phosphorus. Low-carbon killed steel has a good welding effect due to its low impurity content. Both medium and high carbon steel and ordinary alloy steel can be well laser welded, but preheating and post-welding treatment are required to eliminate stress and avoid crack formation.

2. Laser welding of stainless steel. Under normal circumstances, stainless steel laser welding is easier to obtain high-quality joints than conventional welding. Since the heat-affected zone of high welding speed is small, sensitization is not an important issue. Compared with carbon steel, the low thermal conductivity of stainless steel makes it easier to obtain deep penetration narrow welds.

3. Laser welding between various metals. The extremely high cooling rate and small heat affected zone of laser welding create favorable conditions for the compatibility of materials with different structures after the melting of many different metals. It has been proved that the following metals can be successfully welded by laser deep penetration: stainless steel ~ low carbon steel, 416 stainless steel ~ 310 stainless steel, 347 stainless steel ~ HASTALLY nickel alloy, nickel electrode ~ cold forged steel, bimetal with different nickel content.

Therefore, for many laser welding companies, carefully understand the methods and parameters of various steel welding. Therefore, in order to protect laser welding personnel and laser equipment, companies must purchase laser welding fume filters.
