摘要

Based on a large number of CO_2 laser welding tests to hard alloy saw blade cutter by PHC-1300 type laser of 1300W and TEM00 mode, and the laser welding parameters and weld microstructures were analyzed, the mechanical performance tests were also done. The experimental results show that CO_2 laser welding can improve combination strength and bearing capacity of the hard alloy circular saw blade cutter; the laser focal spot offset a distance from the weld line to the center of basal body, which can get the optimal weld line; selecting low carbon alloy steel as matrix material and selecting Co-based alloy as knife head lining material are suitable.
