1. Reasonable design, free adjustment. Different discharge frequencies can be selected according to different metal materials to achieve the best repair effect.
2. Small heat affected area. No heat input during the instant of stacking, so there is no deformation, undercut and residual stress.
3. Very small welding repair shock, the welding machine overcomes the impact of ordinary argon arc welding on the periphery of the workpiece during the welding repair process. It is also safe to repair the workpiece surface without any allowance.
4. High repair accuracy. The surfacing thickness is from a few microns to a few millimetres, just grinding, polishing.
5. Deep hole welding machine welding strong. Strong adhesion due to sufficient penetration into the surface material of the workpiece.
6. Deep hole welding machine adopts ring precision control.
