Abstract
PURPOSE: To break down oxide film, increase diffusion layer and obtain the strong bonding by abutting the fitting surfaces against themselves by electromagnetical pressing force by tapering the faying parts of members at the time of performing electromagnetic solid phase bonding of the faying parts to be bonded by superposing the both 1st and 2nd tubular bar members.
CONSTITUTION: The faying portion of the end part of an outside pipe 11 of an equal thickness and a fixed inside diameter is expanded to trumpet-form to form a tapered faying part 11a. Next, an inside pipe 12 of an outside shape slightly smaller than the inside diameter of the outside pipe 11 and an equal thickness and constant inside diameter is inserted into this outside pipe 11 and its end face is fitted therein up to near the starting part of the trumpet-form, after which a working coil 13 is so disposed as to encircle the outside circumferential surface of the outside pipe of the tapered faying part 11a. Thence, if a high-frequency oscillator 14 is operated and switches 15, 16 are closed, high-frequency voltage is stepped up 17 and is applied to the coil 13, by the strong magnetic field formed by which the both pipes are induction-heated. When the faying parts 11a, 12a become higher than the bonding temperature, the switches 15, 16 are opened to operate a high-voltage power supply unit 18, by which large current is flowed to the coil 13 and the electromagnetic pressing force by induction current is generated, by which the both faying parts are abutted and are pressure-welded.
