Research of welded seam strength of laser welded diamond saw

This article proposes the three major factors influencing the welded seam strength of laser welded diamond saw:(1)selecting proper and well weldable substrate materials;(2)selecting sintering procedure parameters,such as sintering temperature of 650℃～750℃,synthetic pressure of 20 MPa,temperature holding time of 4 min;(3)selecting welding parameters,such as welding power 1kW,welding speed 1m/min,shift amount.0.1～0.25mm.
