摘要： PROBLEM TO BE SOLVED: To provide a method in which a joint part of the comparatively short welding length is beautifully welded at the proper weld bead width by applying electro gas welding to a flange plate to connect at the groove part of its end on the side and the like of the column, and also by making the welding voltage gradually dropped with the progress of welding. SOLUTION: The end of the flange plate 2 with the V shape groove is placed to the side of the column 1 or the diaphragm at a given groove interval, and fixed by a backing metal 3 and a chip metal 4. Then, this groove part is connected by electro gas welding. The welding voltage is controlled so that it may drop gradually as the welding progresses in this case. When the connection part of the construction steel column is connected by electro gas welding, for example, total welding length is divided into four sections and the welding voltage is controlled by each section. In this case, it is desirable that the voltage in the welding starting side is controlled to be higher and the voltage in the welding termination side is lower than the standard voltage of the central part. This prevents the bead width Wb from widening as the progress of the welding.
