Abstract

PURPOSE: To improve the reliability of welding joint through forming stub with welding metal by cutting out the stub from a welding part where beveling groove formed at a tubular hole position in a tube plate is narrow-gap-welded.
CONSTITUTION: At a position where a tubular hole 6 of a tube plate 1 to be worked, a beveling groove 6 having an inner diameter smaller than that of stub, an outer diameter larger than that of the stub and a depth deeper than that of the stub is formed. Next, after the groove 6 is multilayer welded with low heat input through the way of narrow gap welding the stub 8 of welding having the same cross section as a tube is cut out from a welding part 7 through machine work. Then, a tube 4 and the stub 8 are butt-welded through the ordinary welding way.
