PURPOSE:To execute welding by turning a welding head, by turning a turning part to which the welding head has been attached, by using the center of a nozzle as the turning center, and providing a rotary connecting part of a cable, etc. on a fixed part. CONSTITUTION:When a claw 22 of a chuck part C is pressed vertically against the inside surface of a nozzle of a member to be welded, a turning device can be held concentrically with the nozzle. Subsequently, welding is executed by positioning a welding head attached to a fitting plate 2 of a turning part A, in a groove, and rotating a turning table 1. Electric power, cooling water and a shield gas, etc. which are required for this welding are supplied through a power cable 30, a control cable 40, a cooling water hose 50 and a shield gas hose 60, respectively. The cable, etc. are not twisted due to a feed part D1 of a rotary connecting part D, an electric conduction part D2, and a feed water (gas) part D3, and do not become an obstacle to turning of the welding head. |
