EDM welding repair machine principle

Using German advanced cold welder repair and reinforcement technology, using the principle of high-frequency electric spark discharge, the workpiece is subjected to non-thermal surfacing to repair the surface defects and wear of the metal workpiece to ensure the integrity of the workpiece; also can use the EDM welder The strengthening function strengthens the workpiece to achieve wear resistance, heat resistance and corrosion resistance of the workpiece. The electric spark surfacing repair machine does not deform, does not anneal, has high welding strength and is resistant to wear after repairing metal workpieces. It can pass the metallographic, tensile and hardness tests, and the metallurgical bonding of the welding consumables to the substrate ensures the firmness of the welding. Make up for the inadequacies of ordinary argon arc welding and electric welding. The electric spark surfacing machine can repair welding on narrow parts, deep cavity parts and extremely hard materials without cracks or sand holes, nor deformation of the workpiece or depression around the weld pool. The electric spark surfacing machine is protected by argon gas, and the repaired portion does not oxidize bluing. Using the microscope to observe the operation, the small parts can be seen at a glance, and the mirror can be polished after welding, which is suitable for the surfacing strengthening repair of various materials. The welding point of the electric spark surfacing machine can be adjusted to 0.2mm~2.0mm, and it can be welded on the metal plate with the thinnest thickness of 0.2mm, without breaking the plate, and the weld seam is even and beautiful. The electric spark surfacing repair machine is an indispensable repair and strengthening tool for all processing, repair and surface treatment enterprises. At the same time, the electric spark surfacing machine is also a good helper for individuals to quickly get rich in the special repair industry.

Disadvantages of traditional repair: the workpiece is deformed after repair, hardness reduction, blisters, local annealing, cracking, pinholes, abrasion, scratching, undercutting, or insufficient bonding force and internal stress damage or even scrap. The loss of manpower, material resources and financial resources cannot be calculated.
