Document Type and Number:
WIPO Patent Application WO/2020/196547
Kind Code:
A1
Abstract:
This electric conduction heating device brings an electrode into contact with a metal pipe material and performs electric conduction heating of a metal pipe, the electrode being provided with an electrode body part formed from an electrode material, and a displacement-allowing part for allowing displacement of a contact surface for contacting the outer circumferential surface of the metal pipe material, and the displacement-allowing part having an electroconductive member which deforms in the radial direction from the contact surface to the outer circumferential surface more readily than the electrode body part.
