As shown in FIG. 7, a cooling metal fitting 26 is arranged near the mating portion 23 of the plate member, and the inert gas 28 is supplied by the gas nozzle 27.
In the MIG welding method, the metal electrode 29, which is the filler material, is blown to the welded portion so as to wrap it and the welding is performed without being adversely affected by oxygen and nitrogen in the atmosphere. When the overlay welding is completed, finishing work is performed by a grinder or the like so that the welded surface becomes smooth.

ある。However, the heat distortion of the plate member due to the heating by the overlay welding is large and a sink mark is generated. As a countermeasure against this, finishing work is required, in which the plate member is tapped from the back side and the front side is repeatedly ground by a grinder or the like. Since this finishing work requires the skill of the worker and depends on the skill of the individual worker, it may lead to deterioration of the finish quality and quality such as reduction of the plate thickness of the plate member. In addition to the large amount of deposited metal remaining outside the surface of the plate member, there are problems such as an increase in finishing man-hours and a deterioration in working environment due to grinding powder and the like.

An edge portion of one plate member comprises a general portion and a step portion bent in a stepwise manner with respect to the general portion, and the edge portion of the other plate member is superposed on the step portion. In the joining method of the plate members, the welding is performed on the mating portion of the plate member formed by the stepped portion and the end surface of the other plate member, and then the overlay welding part is smoothly finished. The member has a ridge portion protruding to the surface side between the general portion and the stepped portion, and the edge portion of the other plate member has a stepped portion that is bent in a stepwise manner protruding to the surface side. The step portion of the other plate member is superposed on the stepped portion of the plate member, and the welded portion of the plate member formed by the stepped portion and the end surface of the other plate member is subjected to build-up welding, and then the build-up welded portion,
A method of joining plate members, characterized in that a finishing process of grinding the ridge portion and the step portion from the surface side is performed to obtain a smooth surface that is continuous with the general portion of the one and the other members.
