抄録
Recently industrial products and components are being made smaller to reduce energy consumption and save space, and this trend needs to employ an advanced micro welding method for thin foils less than 100μm thick. In this report, in order to examine the applicability of a direct diode laser system with an elliptical beam, butt-, lap- and edge-welding were performed with thin metallic foils less than 100μm in thickness. It was found that the elliptical shape direct diode laser beam was effective to form a weld bead with the narrow width at high welding speed rather than with the ordinary circular laser beam. The direct diode laser with an elliptical beam enabled butt-welding of thin stainless steel foils with the thickness down to 40μm, lap-welding of thin stainless foils of 20μm in thickness onto a thick substrate and edge-welding of INCONEL718 thin foils of 100μm in thickness without crack.
