摘要： A welding method is disclosed for butt welding a first base material 1 and a second base material 2 with each other. To also permit stable and efficient formation of a bead in the form of a fillet weld on a back side of a groove by conducting arc welding from the side of the groove without arranging a bead beforehand on the back side of the groove, the first member 1, on which a root face 1a and a single groove face 1b have been formed, is brought at its root face 1a into contact with a flat surface 2a of the second base material 2. A welding wire 6 is arranged facing on the groove formed by the contact between the first base material 1 and the second base material 2. The first base material 1 and the second material 2 are caused to fuse at an area of contact between them by an arc from the welding wire 6. A melt, which has been formed by the fusion at the area of contact and the like, is forced out to the back side of the groove to form a bead B4 in the form of a fillet weld on the back side of the groove.
