<p><P>PROBLEM TO BE SOLVED: To improve the joining strength of a liquid phase diffusion bonding pipe joint comprising a metal pipe or metal joint of a metal member and a joint pipe or thick-walled metal pipe tapered at the outside surface at one end or both ends joined together by liquid phase diffusion bonding. <P>SOLUTION: A liquid phase diffusion bonded pipe joint comprising metal pipes or a metal pipe and a joint pipe joined by liquid phase diffusion bonding, and a method of production of the same, are provided, the liquid phase diffusion bonded pipe joint comprised of a metal joint provided with a tapered slanted part press-fit into an end of a metal pipe by a thrust in a pipe axial direction while expanding the metal pipe inside diameter and tightly engaging with the end and a joining surface part continuous from the tapered slanted part and joined with an end face of the metal pipe by liquid phase diffusion bonding and a metal pipe tightly engaging with the tapered slanted part in the expanded state and with an end face joined with the joining surface part by liquid phase diffusion bonding. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
