摘要：
The effect of welding voltage on the mechanical properties, including microhardness, breaking susceptibility, and breaking strength, of laser-welded cast titanium (Ti) joints for dental prosthesis was investigated. The four-point bending test was conducted for the evaluation of the breaking susceptibility and strength using a universal testing machine with a crosshead speed of 0.5mm/min. The breaking strength, microhardness and breaking susceptibility were found to decrease with increasing welding voltage. It was also found that the presence of large pores in the weld metal had no effect on the breaking susceptibility of the Ti joint.
