What Materials can the Laser Welding Machine Weld?

Laser welding machines can weld most metals, but the efficiency and effect of different metals are not the same. Many novices are wondering whether they can use laser welding to process their own workpieces. This article will discuss cnc laser welding materials in detail. Hope this article can help your production.

STEEL

The laser steel welding machine can process 136, SKD-11, NAK80, 8407, 718, 738, H13, P20, W302, 2344 and other types of mold steel. And the laser welding steel effect is good.

CARBON STEEL

Laser welding carbon steel can achieve excellent results. In order to obtain good welding quality, heating is required when the carbon content exceeds 0.25%. When steels with different carbon contents are welded to each other, the operator can slightly focus on the low-carbon material side of the torch. This ensures the quality of the weld at the joint. Both medium carbon steel and ordinary carbon steel can be welded well. But the operator needs to carry out heating and post-welding treatment to prevent cracks from forming.

PLASTIC

Laser welding can process almost all thermoplastics and thermoplastic elastomers. Laser welding plastic is common to see in lots of field.

STAINLESS STEEL

In general, laser welding machine for stainless steel is popular now. Compared with carbon steel, stainless steel has low thermal conductivity and high melting efficiency. Therefore, it is easier to obtain deep penetration and narrow welds. laser welding stainless steel with low-power laser can obtain smooth and beautiful welding results.

Copper has a strong heat transfer. So it is easy to cause incomplete penetration and partial unwinding when welding it. Generally, during the laser welding copper, the thin copper material should be heated to assist welding. But handheld laser welding is able to weld in no time. Because its power is concentrated, and the high heat transfer properties of copper are less harmful to it.

ALUMINUM

The biggest difficulty of welding aluminum is its high reflectivity to the laser beam. Aluminum is a good conductor of heat and electricity, and it is a good reflector of light. The initial surface reflectivity is over 90%. That is to say, laser welding aluminum must start with less than 10% input energy. So aluminum laser welding requires a high input power.
