Abstract

PURPOSE: To obtain a product with small weld deformation, having weld zone of metallurgical and mechanical property similar to that of base material, by shaping the material to be welded in such a manner that flat portions are kept on both sides of the groove, and by correcting the shape after welding as in butting of flat plates.
CONSTITUTION: Thin wall sheet to be welded is so shaped that flat, long narrow portions 1' are remained at least on both sides of the original sheet 1 in the longitudinal direction. The shape of the section of the original sheet 1 can be selected optionally in accordance with the size of the vacuum chamber, however it is preferable to have a bending radius as large as possible in order to facilitate the treatment in the later process. Flat sheet portions 1' are butted into each other with or without use of a backing, and welded at suitable intervals so that no gap is made. Thereafter, the sheet is electron beam welded by use of restraining tools to produce primary original pipe A, if necessary, with elimination of reinforcement. Then the original pipe A is shaped into a bellow C directly, or through correction to a secondary original pipe B of high roundness.
