Abstract

PURPOSE: To make possible narrow groove welding by forming the groove end faces suited for narrow groove welding by the welding surface of the welding works and the end face of an auxiliary body by the use of the auxiliary body when the welding surfaces of the welding works are inadequate for narrow groove welding.
CONSTITUTION: When the welding surfaces 1' are, for example, in the case of the square welding works 1, an auxiliary body 2 which becomes a spacer is interposed between the weld zones of the welding works 1, 1 and the both welding works 1, 1 are superposed. The groove end face suited for narrow groove welding is formed by the both welding surfaces 1', 1' and the end face 2' of the auxiliary body 2. Even with the other welding work (not illustrated) of the two, the groove end face is formed in the similar manner. Next, the square groove formed by the both groove end faces is subjected to narrow groove welding, after which the respective auxiliary bodies 2 are removed. According to this method, less welding materials and higher welding performance and welding quality as compared to conventional arc welidng with covered electrode may be achieved.
