Abstract

PURPOSE: To obtain the composite billet excellent in the sealing characteristic, by applying the electron beam welding to the sheath and the block of the composite billet under the mechanically fixed condition.
CONSTITUTION: The block 2, obtained by plurally bundling single core calbes 21 coated with the metal similar to that of the sheath 1, is inserted into the cylindrical sheath 1; the plug 6, made of the metal similar to that of the sheath 1, is attached to the tip of the block 2 and pressed in the longitudinal direction. The tip 11 of the cylindrical sheath 1 is extended out of the trunk 61 of the plug 6. Under the condition that the plug 6 is pressing the block 2, the tip 11 is caulked to the plug 6 in order to fix the cylindrical sheath 1 to the plug 6. This assembly is placed under the vacuum in order to extract the air from the billet, and the electron beam welding 8 is continuously applied to the circumference using the electron beam in order to attain the perfect sealing. Hereupon, the block 2 may be made in one body with the plug 6, or the plug 6 may be set to the cylindrical sheath 1 through the screw thread. Hereby, the high reliable, sound material for the extrusion work can be obtained.
