Field of the Invention The present invention relates to a method and an apparatus for butt welding thick steel plates, and more particularly to a method and an apparatus for welding butt welds between flange plates or between a diaphragm and a flange plate at a column connection. .

うことがができる。2. Description of the Related Art There are two types of column joints, a column penetrating type and a beam penetrating type. Generally, the column joints are formed by multi-layer welding by carbon dioxide semi-automatic welding. In the column penetration type, since the bracket and the stiffener are attached and welded to the column main body, the column members are assembled in a horizontal state, and the welding posture is horizontal. Further, in the beam penetration type, welding is performed by first assembling the connection block, and thereafter, large assembly with the column main body is performed, and welding with the column main body is performed. For this reason, welding of the connection block and the column main body can always be performed in a downward position by changing the position of the connection block.

る。[0003] However, in any case, since multi-layer welding is performed, there is a problem that welding defects due to slag entrainment and the like are likely to occur between the respective welding layers. In particular, in the case of the column penetration type, the condition is more disadvantageous because the welding posture is horizontal. On the other hand, in the case of the beam penetration type, the welding posture is downward, but the posture of the product needs to be changed frequently, and extra work time is required for the posture change, and there is a problem that the work efficiency is poor. .

するものが提案されている(特開平5−27725号)。[0004] From such a point, conventionally, in a welded portion between a column member and a beam, bevel cutting is performed on at least one surface of one or both members of a butt portion thereof.
A groove has been proposed in which a longitudinal groove is drilled at the center in the thickness direction of the end face, the bevel portion is tack-welded, and then the groove portion is subjected to single-layer upward welding by electroslag welding or electrogas welding. (JP-A-5-27725).

ことを目的とする。However, in this conventional method, since the conventional electroslag welding or electrogas welding method in which the welding torch is pulled straight out, the cross-sectional area of the groove that can be welded is limited. As a result, there is a problem that the usable thickness range is limited, and there is a problem that machining of the groove portion is troublesome.
It is an object of the present invention to provide a welding method with a simple groove preparation and a wide usable thickness range, paying attention to such points.
