PURPOSE: To provide a friction welding method by which, manufacturing of a product with such a complicated shape as plural bar like members are erected on a flat plane, an advantage of a friction welding method is utilized such as defects are hardly produced even when a material with inferior weldability and brazing characteristics is used, and in which restrictions on weldable shapes are eliminated so that a satisfactory pressure welding part is obtained regardless of the shape of the face to be joined. CONSTITUTION: A bar-like member 21 is inserted into a hole 32 of a jig 30 while a jig 30 and the bar-like member 21 are each fitted in the notched part 41 and the hole 42 of a jig 40. Then, the rear part of the jig 30 and the bar-like member 21 is supported by the end face of the notched part 41 and the hole 42. As a result, the flat face 31 of the jig 30 and the joining end face of the bar-like member 21 are flush with each other, therefore, joining between new faces are possible by the friction welding with the ring-shaped joining face 22 of a member 23, without exposing the joining face to the atmosphere. |
