laser welding is one inportant aspect of using laser material processing technique . It includes pulse laser welding and continuous laser welding.
Pulse laser welding is mainly used on spot welding and seam welding of thin metal whose wall is under 1mm. The welding process belongs to heat exchange. Its advantage is that the temperature of product doesnt rise much, the heat doesnt affect much and its not easy to make shape change. Continuous laser welding uses high power laser. Its advntage is the ratio of depth and width is big, up to 5:1. The speed is fast and not easy to make shape change.
