What materials can the laser welding machine weld? -Dongguan Laser Engraving Machine

The laser welding machine is an indispensable welding equipment in the welding industry. This welding equipment has many advantages and a wide range of applications. However, many people do not know which materials the laser welding machine can weld. The following is the technology of the Dongguan laser engraving machine Let the staff explain to you:

　1, stainless steel

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

　　2, die steel

　　Laser welding machine can be used for welding S136, SKD-11, NAK80, 8407, 718, 738, H13, P20, W302, 2344 and other materials, and the effect is better.

　　3, carbon steel and ordinary alloy steel

　　Carbon steel is welded by laser welding machine, the effect is good, and the welding quality depends on the impurity content. In order to obtain satisfactory welding quality, 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 biased to the side of the low-carbon material to ensure the quality of the joint. Low-carbon boiling steel is not suitable for laser welding due to its high content of sulfur and phosphorus. Low-carbon killed steel has a very 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.

　　 The above three types of materials can be welded by laser welding machines. Of course, there are far more materials that can be welded. It can be said that laser welding machines can weld a lot of materials. It is believed that the prospect of laser welding machine in the future development road will become more and more broad.
