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

It is a new type of welding, mainly for thin-walled materials, precision parts welding, can achieve spot welding, butt welding, stacking welding, sealing welding, etc., depth and width ratio, small weld width, small thermal impact zone, small deformation, welding speed, weld formation, beautiful, no need to treat after welding or just simple treatment, high weld quality, no stomata, Can be precisely controlled, small focus light point, high positioning accuracy, easy to achieve automation.
