Abstract
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 memberwith a holewhich has the same geometry as a cross section of a forcibly inserted portion of a second member; and the second memberhaving a constant cross section over its length which is similar in shape to the holewherein a press-fit interference of the second memberrelative to the holeof the first memberis set to 0.1 mm or more; wherein the second memberis pushed against the holeof the first memberunder 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 memberinto the holethereby forming a joint interface between the second memberand the inner wall surface of the holewherein the joint thus formed is a solid-state welded joint.
