Abstract

PURPOSE:To junction each fixed pipe by friction pressure welding, by inserting the third pipe body into the middle of a pair of static pipe bodies, rotating it, forming a boundary face in a molten state by friction heat, and after that, putting pressure force onto the third pipe body, stopping it suddenly, and cooling it. CONSTITUTION:A pipe body 1 and 2 are statically fixed by a jig 4, and after that, a pipe body 3 is rotated at a high speed together with a jig 6 by a power source 5. In this case, the contact face of the pipe body 3 and the jig 6 is fixed by a key 7 so that it does not slide. Subsequently, both boundary faces of the pipe bodies 1, 2 are formed in a molten state by friction heat in case of rotation, and after that, by putting pressure force onto the rotating pipe body 3 from the direction Y by a pressure mechanism of the jig 6, the thick face of the pipe bodies 1, 2 is entirely covered, it is stopped suddenly, and in a state that the pressure force is held, the pipe body 3 is cooled.
