[0002] Parts corrosion is the main cause of damage to mechanical equipment. The quality of the anti-corrosion ability of parts is directly related to the safe operation of mechanical equipment. It is a recently developed anti-corrosion technology to clad alloy powder on the surface of the workpiece by laser, but the use of alloy Powder laser cladding technology still has problems such as low cladding efficiency, many defects, high cost, and large dust.

[0003] Laser cladding of wire material can solve the above problems very well, but due to the influence of the base material and welding wire on the laser absorption rate, non-fusion phenomenon often occurs. For this phenomenon, the laser power can be increased, but increasing the laser power will cause Increase the dilution rate and cause a waste of energy, so if the welding wire can be heated before entering the molten pool, the above problems can be solved very well, and a high-quality fusion effect can be achieved without increasing the laser power. The heating effect of the heating wire device for preheating the welding wire is not good, and the phenomenon of wire jamming or wire stripping often occurs, resulting in the inability to work continuously for a long time, which hinders the development of laser cladding technology for wire materials
