Abstract

PURPOSE:To assure perfect penetration in a T type welded joint easily at a low cost and in a short time by placing a weld bead beforehand on the welding part of a welding member that cannot be prepared of edges, installing a mating welding member thereon and executing root pass welding. CONSTITUTION:A weld bead 7 is placed beforehand on a welding member 2 which is installed on a horizontal plane or in the state of having certain inclination, and which cannot be prepared of edges. A welding member 1 prepared with an edge is joined to this bead 7 perpendicularly or by having certain inclination, whereby a groove 4 is constituted. The root pass weld beads for the purpose of effecting perfect penetration are made by generating the arc in the joined part of the member 1 and the unmachined bead 7. By constituting the groove 4 in this way, the heat pulling of the member 1 and the bead 7 during arc welding is made uniform and the uniform and perfect penetration welding is accomplished.
