Laser welding is suitable for a wide range of materials. By mastering the process changes in some common metal laser welding, you can achieve better performance for the weld seam and welding quality of metal laser welding.

Stainless Steel Metal Laser Welding:

  According to experiments, the thermal conductivity of stainless steel is only 1/3 of that of carbon steel, and the heat absorption rate is relatively high. Therefore, stainless steel can be welded with a higher depth of penetration than carbon steel in the welding process. Laser welding itself has small heat input and fast welding speed, which is very suitable for processing and welding of Ni-Cr series stainless steel.

Laser welding of copper, aluminum and its alloy metals:

  Usually the unweldability of brass is due to the content of zinc in it that exceeds the range required for laser welding. Zinc material itself has a low melting point and is very easy to vaporize, which will lead to serious welding defects such as pores and bubbles.

  Due to the high reflection and thermal conductivity of aluminum alloy materials, relatively high energy density is required during laser welding. However, many aluminum alloy materials contain a large number of volatile elements, such as silicon, magnesium, etc., which lead to many pores in the weld. However, this phenomenon does not occur in the laser welding of pure aluminum materials.

  This laser welding machine from Hanteng is small in size, easy to move, low in equipment operating cost, less consumables, simple in daily maintenance, and reduces the cost of line shutdown and debugging; compared with traditional welding, it can implement non-contact long-distance welding; Wide range of welding materials: stainless steel, carbon steel, galvanized sheet, brass, aluminum alloy sheet and other metals.
