摘要： A forced-insertion welded structure is provided which is formed by welding members making up a metal component and which is easy to manufacture and has low cost, a good finish precision and a high bonding strength. The forced-insertion welded structure comprises: a first member 2 with a hole 13 which has the same geometry as a cross section of a forcibly inserted portion of a second member; and the second member 4 having a constant cross section over its length which is similar in shape to the hole 13; wherein a press-fit interference of the second member 4 relative to the hole 13 of the first member 2 is set to 0.1 mm or more; wherein the second member 4 is pushed against the hole 13 of the first member 2 under a predetermined pressure and at the same time an electric current is applied between the two members to generate electric resistance heat in faying portions of the two members to forcibly push the second member 4 into the hole 13, thereby forming a joint interface between the second member 4 and the inner wall surface of the hole 13; wherein the joint thus formed is a solid-state welded joint.
