The technique to weld stainless steel with fiber lasers was investigated. The main objective of this study was to determine the influence of the welding parameters, such as laser power, defocusing amount, velocity, on weld characteristics. The mathematical model was put forward. And, the temperature and thermal stress distribution in the welding process was calculated by ANSYS. Through numerical prediction, the theoretical effects of laser parameters to the welding quality were analyzed.
