Regarding the welding method in which the attached plate is further welded to reinforce the joint after welding (hereinafter referred to as saddle welding), the precision of multi-layer excess welding is particularly important when automatically welding the outer peripheral edge of the plate. 1) Provides a method for welding the outer periphery of a backing plate that can be easily performed.

面で問題があった。When carrying out the saddle welding described above, there is a level difference (height difference) in the direction of the center axis of the nozzle on the outer peripheral end surface of the plate, and the end surface is formed so as to be orthogonal to the cylindrical main pipe. When attempting to uniformly weld the outer peripheral end face with a welding torch, it is necessary to control the inclination angle of the torch axis so that a constant angle is maintained with respect to the end face, and furthermore, The welding in this area is a multilayer weld, and if the welding reversal position near the outer peripheral end face is too close, an undercut will occur, and if it is too far, the welding strength will decrease, so it is necessary to perform reliable position control. Conventionally, there is no automatic welding equipment that can be used for this purpose, so manual welding by skilled technicians has been relied upon, resulting in low productivity and processing costs. There was a problem.

By realizing a control means, it is possible to promote automation of this type of welding and to achieve stable welding accuracy.

This is characterized by a welding method in which the joint is reversed at this welding reversal position, and while the distance and angle to the outer peripheral end face are held constant, the distance from the outer peripheral end face is also maintained constant at the welding reversal position. Automatic control is now possible, which makes it possible to achieve the two desired objectives.

で問題はない。However, the welding along the outer circumferential end surface (6) is a multilayer welding as shown in Fig. 5, and it is necessary to weave each welding layer, but the position of the X axis for weaving is The welding reversal position (A1) that serves as the reference point for the first layer, that is, the reversal position closer to the outer peripheral end surface (6), is the position stored when tracing with the tracing stylus (8) for teaching before welding. There is no problem as long as it is based on the take.
