Abstract

PURPOSE: To shape and treat back beads efficiently and obtain the sound back beads by enclosing the end part of the welding beads formed by welding with the back face opposing to the weld zone over the specified depth and heating from the back side to remelt, after welding by the captioned method.
CONSTITUTION: The back beads 5 of the electron beam weld zone 4 where undulations are large and weld defects such as undercuts and root defects are produced are remelted by a heat source 7 of 104w/cm2 or less in energy density. If the beads are remelted by the high-pulse TIG welding method or the like composed of such a heat source, the melt width is extremely wider as compared to the weld width of the electron beam weld zone; moreover the bead appearance is even and small in undulations, where the formation of weld defects is not observed.
