Embodiment Construction
[0106] The present invention will be further described below in conjunction with accompanying drawing;
[0107] figure 1 As shown, it is the state diagram of laser brazing cladding copper alloy layer on the surface of the ring steel base. On the laser machine, the ring steel should be clamped firmly, concentric front and rear, and rotate at a constant speed. Rotate clockwise for laser irradiation, and return counterclockwise for cooling .
[0108] The carrier gas argon is used in conjunction with the powder feeder to make the powder feed uniform.
[0109] The laser beam moves parallel to the ring steel synchronously to make the irradiation uniform and prevent surfacing.
[0110] The power of the laser beam should be consistent, the value should be reasonable and moderate, the laser irradiation should be controlled according to the program, rotate at a constant speed according to the helix angle, and irradiate the ring steel with a single starting point and end point.
