Advantages of repair:
1. Complete metallurgical fusion, firm solder joint, can withstand all kinds of turning, milling, planing, grinding and other mechanical processing without falling off.
2. The metallographic structure of the matrix does not change, no stress concentration, no deformation and no crack.No annealing or quenching will occur.Third, the repair trace is small and the solder waste is less.4. It is easy to operate.The machine is light and convenient, and the welding position is flexible, so it is unnecessary to dismantle large workpieces. V. safe operation, no poison, no smoke, no light, no dust, no noise and no environmental pollution
