[Prior art j] In hot rolling, when the rear end of a preceding rolled material and the leading end of a subsequent rolled material are butt-pressed and joined, oxide scale is attached to the surface of the rolled material. There is a problem in that it is difficult to obtain the required bonding strength. Therefore, conventionally, before abutting, the abutting surfaces are descaled in advance using a scale removing device, and then the abutting surfaces are abutted and pressure welded.

[Problems to be Solved by the Invention] However, in the case of the above method, it is actually quite difficult to butt the parts within a short time after descaling, so oxide scale grows on the butt surfaces again and reduces the bonding strength. There is a problem of lowering the value.

[Operation] In the method of the present invention, by rotating the spin plug at high speed, frictional heat is generated at the contact surface between the spin plug and the rolled material.
