Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of welding, in particular to an automatic laser welding machine. Background Art
[0002] Laser welding is a highly efficient and precise welding method that exploits the interaction between a laser beam and metal. When the laser beam strikes the metal surface, it absorbs the laser energy and rapidly heats up, forming a liquid or gaseous molten pool or vaporization pore. As the laser beam moves, the molten pool or vaporization pore extends along the weld seam, ultimately achieving a weld connection.
[0003] Existing laser automatic welding machines need to weld different locations on the surface of metal parts during welding operations. To reduce the structural complexity of the equipment, welding at different locations on the metal parts is usually performed by rotating the two metal parts. However, during the rotation process, the two metal parts may shift, affecting the welding accuracy and resulting in reduced welding results. Therefore, we propose a laser automatic welding machine to solve the above-mentioned problems. Utility Model Content
