METHOD FOR WELDING ONE SIDE OF STEEL-FRAME STRUCTURE

摘要

PURPOSE: A method for welding one side of a steel-frame structure is provided to perform welding by processing corners of the welding member and the overlay welded part after overlay welding the back surface of the cross-sectional part of a welding member. CONSTITUTION: In a method for welding one side of a steel-frame structure, the method comprises the processes of processing corners of the cross-section(2T) of a welding member including the overlay welded metal(9) after holding a material(8) such a carbon plate which is not fused by a welding heat source onto one end of a "T" shaped welding member(2) or one side of both sides of a butt welding member in which two members form the almost same surface, and overlay welding(9) between the back side of the cross-sectional part(2T) of the welding member(2) and the material(8) that is not fused by a welding heat source; and weld bonding the welding member(2) as fusing the groove surface of the overlay welded metal(9) at the surface side of the groove by oppositely directing the welding member(2), thereby securing a welding thickness in a plate thickness direction surpassing a plate thickness of the cross-section(2T) of the welding part.
