Abstract

Abstract. In order to identify the evolution of joint formation about crossed wires of Pt-10% Ir to 316 LVM SS in laser microwelding, the experimental and computational study was carried out. The results showed that, with the increase of peak power of laser microwelding, the laser joint evolution of the crossed-wires appears a transition from a laser braze to a fusion weld. The simulation of joint was agreed with the experimental results.
