Summary:Laser welding are well reported to be excellent in precision parts joining with high reputations in external finishing. However, the process in obtaining the best processing parameters is not an easy task. In the case of pulse wave laser, the parameter setting constrained by the laser generator specification. Each laser parameters such as pulse width tp, pulse repetition rate fp and average laser power Pavg has relation which others. Increasing one parameter will directly decreases the maximum value of other parameters. The limited applicable combination and rage of processing parameters make it difficult to obtain the optimized processing parameters. This study is conducted to investigate the influence of each lasing parameters on the welding penetration capability. The range of applicable parameters for titanium alloy sheet metal has been successfully clarified
