PURPOSE:To prevent the occurrence of defects in weld zones when four members are assembled into a capsule by welding, by carrying out welding at positions away from the corners so as to relieve stress produced in the weld zones. CONSTITUTION:A metallic capsule for HIP is composed of a bottom wall, a tubular wall and a top wall having a degassing pipe. At this time, a bottom wall 1, a tubular wall 2, a top wall 3 and a degassing pipe 4 having shapes obtd. by dividing a capsule along planes which meet at right angles to an axial direction at positions away from the top and bottom are prepd. and those four elements are welded in vacuum or an inert gaseous atmosphere. |
