Laser welding machine is a new kind of welding process, mainly for welding thin-walled materials and precision parts, spot welding, butt welding, staple welding, seal welding, etc. can realize. Material laser welding machine can weld precisely.
What are the operation steps of laser welding machine?
What materials can laser welding machine weld?
How does laser welding machine weld carbon steel?
1. First, make preparations before starting the laser welding machine, including: check the power supply of the laser welding machine and whether the water circulation is normal; check whether the gas connection of the equipment in the laser welding machine is normal; check whether the surface of the machine is free of dust, spots, oil, etc. .
2. After the laser welding machine is checked normally, it can be turned on, that is, turn on the power supply, turn on the main power switch; turn on the water cooler, laser generator, etc. in sequence; open the argon gas valve, and adjust the gas flow; working parameters; perform welding operations.
3. After the operation of the laser welding machine is completed, the last step is to shut down. First, exit the program and turn off the laser generator; turn off the dust remover, water cooler and other equipment in sequence; turn off the argon cylinder valve; turn off the main power switch.
laser welding machine can weld carbon steel, die steel, alloy steel, stainless steel, titanium, nickel, tin, copper, aluminum, chromium, niobium, gold, silver and other metals and their alloys, as well as steel, Kovar and other alloys. The welding between the same materials can also meet the laser welding between different steels.
Laser welding is the use of high-energy laser pulses to locally heat the material in a small area. The energy of the laser radiation diffuses into the interior of the material through heat conduction, and the material is melted to form a specific molten pool. It is a new type of welding method, mainly for the welding of thin-walled materials and precision parts, and can realize spot welding, butt welding, stitch welding, sealing welding, etc. Small deformation, fast welding speed, smooth and beautiful welding seam, no need or simple treatment after welding, high welding seam quality, no pores, precise control, small focusing spot, high positioning accuracy, and easy automation.
Carbon steel is welded by laser welding machine, the welding effect is good, and the welding quality depends on the impurity content. In the case of carbon content greater than 0.25%, in order to obtain good welding quality. When steels with different carbon content are welded to each other, the welding torch can be biased towards low carbon materials to ensure the quality of the joint. Because the heating and cooling speed of laser welding machine is very fast, so when welding carbon steel. The higher the carbon content, the higher the susceptibility to weld cracks and nicks. Medium and high carbon steel and ordinary alloy steel can be laser welded well, but stress should be relieved to avoid cracking.
