Laser welding is the use of high-energy laser pulses to the material in the small area of local heating, the energy of laser radiation through the heat conduction to the internal diffusion of materials, the material melted into a specific pool.

It is a new type of welding, mainly for thin-walled materials, precision parts welding, can realize spot welding, butt welding, overlay welding, sealing welding, deep width ratio, small weld width, small heat affected area, deformation small, welding speed, weld formation, aesthetics, no need to deal with after welding or simply treatment, weld quality is high, no blowhole, Can be precisely controlled, focus light point small, high positioning accuracy, easy to automate.
