Laser welding is a new type of welding method, which has the advantages of fast welding speed, small weld width, small heat-affected zone, small thermal deformation, smooth and beautiful weld seam, etc. The types of automatic laser welding function welding mainly include pulse laser welding, plasma arc welding, continuous laser welding, electron beam welding and so on.
Pulse laser welding: pulse laser welding is mainly used for single-point fixed continuous welding and low-power seam welding (such as welding of thin materials), and the general welding thickness does not exceed 1mm.
Plasma arc welding: This welding method is similar to argon arc welding. The torch generates a compressed arc to increase the arc temperature and energy density, but it is faster than argon arc welding and has a larger penetration depth, but slightly inferior to laser welding.
Continuous laser welding: This welding method is mainly used for the welding of large and thick parts, and a continuous weld seam is formed during the welding process. Welding materials, welding equipment brands, etc. will all affect the welding effect.
Electron beam welding: This welding method uses accelerated high-energy-density electron flow to hit the workpiece, generating huge heat in a small dense area on the surface of the workpiece, forming a small hole effect, thereby achieving deep penetration welding. The disadvantage of electron beam welding is that high vacuum needs to avoid electron scattering, the equipment is complicated, the size and shape of weldments are limited by the vacuum system, the quality of butt weldment assembly is strict, and non-vacuum pump electron beam welding can also be implemented, but due to electron scattering However, the focus point is not very good, which affects the results, and the tools of electron beam welding products need to be demagnetized before welding.
Different types of welding are suitable for different welding process requirements.
