Numerical modeling has been carried out to analyze thermal characteristics for laser diode welding machine. Laser diode welding machine performance is largely affected by the applied current and welding period. Unsteady thermal characteristics near the laser diode welding cap has been analyzed, and most simulations were performed after applying electrical current for the duration from 0.1 to 0.5 second. Those results from this study could be applicable to the design of optimal operating condition for the laser diode welding machine system.
