Abstract: PURPOSE:To reduce the lose time such as deposition of a chip on a work by detecting continuity between a welding torch and an electrode or between a welding wire and base metal and stopping welding work temporarily in the case of no continuity between these in welding of a second and subsequent layers of multilayer welding. CONSTITUTION:In welding of the second and subsequent layers of multilayer welding, continuity between the welding wire and the base metal is detected by a detector 9 and when continuity is not obtained due to slag, welding work is stopped temporarily. Hereby, a failure of the arc generation is prevented or it is prevented that the wire comes into contact with the base metal other than a bead and an explosive arc is generated and the chip is deposited on the work. In addition, when the welding wire is moved till a next pass starting end before the slag becomes solid at a terminal of each pass of multilayer welding and the voltage is applied thereto, continuity between the bead and a metal part is confirmed. Further, when the interval between the welding wire and the base metal is continued and the arc is generated, it is not necessary to move quickly the welding wire till the next pass starting end before the slag becomes solid. By this method, reliability of the arc start of multilayer welding is improved by simple control.
