Abstract

PURPOSE: To prevent the occurrence of cracking and breaking of the weld zones owing to fluctuating internal pressure by projecting the ends to be welded inward of a structure and forming single-bevel grooves of long legs between said ends and materials to be welded in welding the structure from the outer side by an inverted L type joint system.
CONSTITUTION: Side plates 3, 4 are butted to the end face of a bottom plate 2, and fillet welding 5, 6 is carried out from the inner side with sufficient leg length. A cover plate 7c is beforehand bent by plastic working in such a way that its both end parts project inward at an obtuse angle, whereby projections 12c, 13c are formed. The cover plate 7c is inserted between both top ends of side plates 3, 4 from above to form single-bevel groove parts 14c, 15c to the cover plate 7c and the side plates 3, 4 to long legs. These parts 14c, 15c are welded from the outside, whereby inverted L type welded joint parts are formed. Thence, end plates are welded to the end faces in the front and rear directions of the bottom plate 2, the side plates 3, 4 and the cover plate 7c, one from the inner side and the other from the outer side respectively similarly by an inverted L type welded joint system.
