【Abstract】 In this study, experiments and analysis were conducted on the two types joints of tailored-blank welding. The welding was performed by a Nd:YAG laser with 2 kW maximum power combined with a robot arm. Lap welding & butt welding of two different thickness workpieces were investigated. After welding, the tensile test of welding joints were conducted, and the appropriate welding parameters were ascertained.更多还原
