With its high brightness, high directivity, high coherence and high monochromaticity, laser has been widely used in various aspects of life and scientific research, such as laser welding, laser cutting, laser drilling, laser acupuncture and moxibustion, laser cutting, etc. In laser welding, high-energy laser pulses are used for locally heating materials in micro-areas, energy radiated by laser is diffused into the materials through heat conduction, and the materials are melted to form a specific molten pool. The laser welding method is a novel welding mode, mainly aims at welding of thin-wall materials and precise parts, can realize spot welding, butt welding, stitch welding, seal welding and the like, has high depth-width ratio, small weld width, small heat affected zone, small deformation, high welding speed, flat and attractive weld joint, does not need to be processed or only needs to be simply processed after welding, has high weld joint quality, no air holes, can be accurately controlled, has small focusing light spots and high positioning precision, is easy to realize automation, and is one of important aspects of laser material processing technology application. A laser welding method using a welding robot that moves a laser head to weld a plurality of positions of an object to be processed is used in a production line such as an automobile as a technique that replaces resistance welding. Resistance welding is welding in which overlapped metal members are partially joined by sandwiching the tips of electrodes and applying pressure to the welded portion while passing a current.
