摘要：

Present study was performed to determine the welding conditions for sound welding, efficiency and process of bead formation using Yb fiber laser for ultra thin metal foil (SUS304, thickness: 10similar to60mum). The influence of assist gas was investigated by the measurement of bead width at different gas flow rate and the conditions of keyhole welding was estimated with metal foil. Relationship between experimental results and thermal conduction calculation based on moving line heat source model was also investigated. Sound lap welding of 20mum to 30mum thickness was obtained.
