Laser welding is the use of high-energy laser pulses to locally heat materials in small areas. The energy radiated by the laser diffuses through the interior of the material through thermal conduction, melting the material and forming a specific molten pool.
It is a new type of welding method mainly used for welding thin-walled materials and precision parts, which can achieve spot welding, butt welding, overlay welding, sealing welding, etc. It has a high aspect ratio, small weld width, small heat affected zone, small deformation, fast welding speed, smooth and beautiful weld seam, and does not require or only requires simple treatment after welding,
High weld quality, no porosity, precise control, small focusing spot, high positioning accuracy, easy to achieve automation.
