Abstract

Welding process of ultra thin stainless steel foil was investigated using a single mode Yb-fiber laser with a CW maximum output power 40W. In micro welding, critical power density for keyhole welding was 1 to 2 orders larger higher than in macro-welding due to larger thermal conduction, extremely high speed welding becomes possible.
