Material suitable for laser welding

Material suitable for laser welding Material suitable for laser welding is as follows: 1, mold steel. S136, SKD-11, NAK80, 8407, 718, 738, H13, P20, W302, 2344 are better. 2, laser welding of carbon steel and ordinary alloy steel. In general, the carbon steel laser welding effect is good, and its welding quality depends on the impurity content. Like other welding processes, sulfur and phosphorus are sensitive factors that produce welding cracks. In order to obtain satisfactory welding quality, preheating is required when the carbon content exceeds 0.25%. When the different carbon-containing steel is welded to each other, the torch can be slightly deflected as the low carbon material to ensure the quality of the joint. Low carbon boiling steel is not suitable for laser welding due to high content of sulfur and phosphorus. Low-carbon town static steel is very good because of the low impurity content. In the medium, high carbon steel and ordinary alloy steel can carry out good laser welding, but preheating and welding treatment is required to eliminate stress to avoid crack formation. 3, laser welding of stainless steel. In general, stainless steel laser welding is more likely to obtain a quality joint than conventional welding. Due to the high welding speed thermal affected area, sensitization is not an important issue. Compared with carbon steel, the low thermal conductivity of stainless steel is more likely to obtain deep molten welds. 4. Laser welding between different steels. Laser welding is extremely high cooling speed and small thermal influence zone, which has created favorable conditions for materials with different structures after melting many different metal welding. It has been proved that the following metal can smoothly carry out laser deep split welding: stainless steel ~ low carbon steel, 416 stainless steel ~ 310 stainless steel, 347 stainless steel ~ Hastally nickel alloy, nickel electrode ~ cold forging steel, Different nickel content double metal strips. 5, titanium, nickel, tin, copper, aluminum, chromium, niobium, gold, silver and other metals and alloys of alloys, and steel, molten-free alloys. Welding. Nonferrous metals are relatively welded, and their copper alloys, and silver alloys are the most difficult to weld. 6. Application of copper-nickel, nickel-titanium, copper-titanium, titanium-molybdenum, brass-copper, low carbon steel-copper, etc. Welding.

The impact of the coating on laser welding: the high-graphic plating is difficult to weld: mirror chrome plating, silver plating, silver plating, etc. General plating is relatively welded: nickel plating, galvanized, copper plating to welding strength without affecting high polishing metal is refractor welding: copper Silver, gold welding strength is less residual: as long as it is not a large gap on laser welding: the smaller the seam, the better the appearance, the strength is larger, and more severe groove welding Sewing, the strength is also small. The impact of material thickness on laser welding: the material, welding difficulty, and the welding seam will be deformable, and the welding is small. Thicker material, the welding appearance is better, and the strength is also large. , Reading the full text, the technology area Universal Board _Welding Skills for Cave Boards (Precautions) How to get a chip without a hot air?
