Abstract
The characteristics of micro-welding for thin stainless steel foil were investigated using high speed laser scanning with both single-mode fiber laser and pulsed Nd: YAG laser. The overlap welding of 25 um thickness sheet could be successfully performed using a laser beam with a small focus diameter, regardless of the presence of a small gap between two sheets.
Keywords: foil, fiber laser, Nd:YAG laser, high-speed scanning, micro-spot
