Abstract

In this study, the characteristics of laser micro-welding with a high-speed scanning system on thin stainless steel sheets by using a single-mode CW fiber laser were experimentally investigated. It was clarified that the welding bead width and depth increased when increasing the scan velocity under a constant energy density condition, and high efficient welding was expected by using high-speed laser scanning with Galvano scanner. The utilization of assist gas is found to be very effective to obtain smooth fusion bead. In addition, the combination of micro beam spot and high-speed laser scanning made it possible to obtain good overlap welding of ultra-thin stainless steel sheets.
