Abstract
PURPOSE: To stabilize the quality of joined surfaces by diffusion welding by hermetically mounting caps to both ends of an outside pipe, putting the joined part of the outside pipe and an inside pipe in a vacuum or inert atmosphere and heating these in an atmospheric furnace.
CONSTITUTION: Caps 6, 6' are mounted to both ends of an outside pipe 1 which is an object to be welded assembled with the outside pipe 1, an inside pipe 2, and a metallic round bar 3, thereby hermetically sealing the inside of the pipe 1. An exhaust pipe 7 is provided to the one cap 6' to evacuate the inside and to put only the joined surfaces of the pipe 1 and the pipe 2 in a vacuum or inert atmosphere. When this object to be welded is heated to the correct temp. for diffusion welding in a heating furnace 12 in the atmospheric air, the pipe 2 is pressed to the pipe 1 by the expansion of the bar 3 having a coefft. of thermal expansion larger than that of the pie 1 and the pipe 2, whereby a clad pipe or the like is manufactured.
