PROBLEM TO BE SOLVED: To reduce troubles such as the concentration of stress, the increase in the number of stages and unstable welding in a backing strip welding method, a penetration welding method, a bead placing method, a build up welding method or the like where a penetration bead is formed on the rear side of a bevel, in a single welding method for a construction steel frame and steel pipe structure. SOLUTION: Regarding butt welding of a beam flange orthogonal to a wide flange shape column or a square steel pipe column and butt welding of a stiffener orthogonal to a wide flange shape column or a beam, horizontal fillet welding or vertical fillet welding is performed respectively from the opposite side of a single-bevel, and a table wave bead is formed on the surface side of a bevel.
