Abstract :
Tensile shearing tests are used to investigate the mechanical property of laser welded Ti-6Al-4V lap joints. The load per length of weld bead is introduced to evaluate the bearing ability of laser lap joints, and the failure load ranges from 394 to 502N/mm. The optima parameters for 0.8mm thick Ti-6Al-4V alloy is 1800~2350W laser power and 1.5~2.5m/min welding velocity.
