Laser welding has many advantages, such as low heat input, narrow welding beads, and small residual stress and deformation. Laser welding is widely applied in industry. By combining with automation system, laser welding can be integrated into current production line and significantly improve production speed. In this paper, we will introduce the mechanism of laser welding and the step energy control technology for laser welding. The step energy control technology solved the hole-defects commonly found at the end of laser welding process. The technology provided a high speed and high quality laser welding process. We also introduce laser welding results in different materials, such as carbon steel, stainless steel, copper and aluminum.
