ABSTRACT:
For repairing a metal member by welding, a secondary electrode is connected to the metal member to be repaired. A thin sheet type welding material of about 0.1-0.2 mm thickness is provided on a part of the metal member or a fine welding powder of a proper volume is piled up on there. The welding material or the welding powder is pressed to the metal member along a minute line or dots by a primary electrode and an electrical conduction path is formed. A large pulse current of about 300-1500 amperes is applied through the conduction portion during a short period of about 1/1000-4/1000 seconds to form nuggets of a minute line or dots on the metal member. Thus, a build-up welding can be done along dots or a line. A part of the build-up welded portion is worn away and ground to obtain a desired surface or shape. A permanent magnet or an electromagnet may be mounted at the primary electrode when the welding powder is used.
