Abstract

PURPOSE: To simultaneously manufacture plural thin walled metal pipes with little thickness irregularity at the rigidly pressure welded lap joint, by giving the press force uniformly to each pressure welding jig parallelly installed through the pressure block.
CONSTITUTION: The core bar 5 is inserted into the metallic tubular body 4 being formed by lapping the taper zones 2, 2', of the thin metal sheet 1; after that, these are set in the pressure welding jig 9 consisting of the upper forming jig 7 and the lower forming jig 8 both being provided with the semicircular groove 6; thus, the set 10 is assembled. Next, plural sets 10a... are similarly assembled, and are transversely parallelly laid on the lower bed 13 of the press 12; thereafter, the round bar type pusher 15, made of a metal possessing the melting point higher than that of the tubular body 4 and being soft at the pressure welding temperature, is laid on the concave groove in the upper surface of the jig 7. then, the upper bed 14 is brought down so as to catch each set 10a... through the block 15 together with the lower bed 13; under this condition, the set is inserted into the hot pressure welding furnace 16. Above stated each set is heated within the nonoxidizing atmosphere of the furnace 16, and also, the upper bed 14 is brought down to impress a strong press force so as to cause the diffusion welding between the lap joint 3 of the tubular body 4... in each set 10a...; hereby, the lap joints 3 are pressure welded and plural thin walled metal pipes of desired shape are simultaneously manufactured.
