Laser welding machine for mold and metal workpiece wear, scratches, pinholes, cracks, defects, deformation, hardness reduction, sand holes, and other defects for deposition, sealing, repair equal function. After repair, the matrix does not deform, does not anneal, does not bite and does not have residual stress, does not change its metal organization state, high repair precision, coating thickness from a few microns to a few millimeters, just grinding and polishing. High power argon protection, can work for a long time. Laser beam energy adjustable, moving speed adjustable, can be a variety of welding processing.
