Abstract

PURPOSE: To enable sound welded joints to be readily obtained by providing divergent opening grooves to the I type groove end parts of butted thick-walled materials and arc welding the grooves after electron-beam welding the I type grooves in welding the thick-walled materials by an electron beam welding method.
CONSTITUTION: Grooves 1c, 1d which open divergently toward end faces respectively are provided to both front and back end parts of the square grooves 1' of the thick-walled materials 1a, 1b to be welded. It is desirable that the shape of the divergent grooves 1c, 1d be of such a shape and size which may be covered by one pass of submerged arc welding. Next, the butt faces are electron-beam-welded to obtain weld zones 2, aftr which the grooves 1c, 1d are arc welded.
