、空気の侵入を防ぐために溶接した。5US304 thickness 2.0nIII! A hoop with a width of 1.2 m was cut to match the circumferential surface of the rough material, and it was coated on the surface of the base material of the rough material as a laminate using a roll forming machine, and the butt parts were welded. It was made into a pipe-shaped coating. In addition, the boundaries between the base material and the laminate material at both edges of the rough material were also welded to prevent air from entering.
