Abstract

Application for laser welding have increased steadily in recent years due to its benefits such as high speed, high productivity and high density energy heat source. In this article these advantages of the laser welding has been considered for Nd:YAG laser stitch welding as a substitute for spot welding of lightweight car body plates. Optimized parameters for Nd:YAG laser stitch welding have been determined comparing the economical and mechanical characteristics to match with the currently used spot welding characteristics.
