Cold welding machine (cold welding machine for repairing metal defects) can deposit, seal and remedy the defects such as wear, scratches, pinholes, cracks, defect deformation, hardness reduction, sand holes and damage of metal workpieces. A wear-resistant layer, a corrosion-resistant layer, a heat-resistant layer, an oxidation-resistant layer, an impact-resistant layer, an anti-slip layer, a high adhesion layer, a solderable layer, a conductive layer and the like can also be formed on the metal surface.
The first-class metal repair cold welding machine (mold repair cold welding machine) does not produce thermal deformation, crack and hardening in use, and can be repaired at room temperature without affecting machinability, and can be used for post-treatment such as turning, milling, planing, grinding, polishing and electroplating.
Both blank parts and finished parts can be repaired directly.
