Abstract
In a method for cleaning a portion to be welded in which a first portion (Pa) to be welded and a second portion (Pb) to be welded, which are to be joined by butt welding, are cleaned, the first and second portions (Pa, Ph) to be welded are cleaned before the butt welding by injecting, with the first and second portions (Pa, Pb) to be welded abutting on each other, plasma produced from a gas containing oxygen into a groove between the first portion (Pa) to be welded and the second portion Pb) to be welded.

A method for cleaning a portion to be welded in which a first portion to be welded and a second portion to be welded, which are to be joined by butt welding, are cleaned, wherein
- the first and second portions to be welded are cleaned before the butt welding by injecting, with the first and second portions to be welded abutting on each other, plasma produced from a gas containing oxygen into a groove between the first portion to be welded and the second portion to be welded.
A welding system that performs butt welding, comprising:
- a cleaning head that cleans a first portion to be welded and a second portion to be welded, which are portions to be welded, by injecting, with the first and second portions to be welded abutting on each other, plasma produced from a gas containing oxygen into a groove between the first portion to be welded and the second portion to be welded;
- a welding head that performs butt welding of the first and second portions to be welded;
- and
- a moving device that moves the cleaning head and the welding head relative to the groove, wherein
- after the cleaning is performed by moving the groove and the cleaning head relative to each other by the moving device, the groove and the welding head are moved relative to each other by the moving device to perform the butt welding.
A method for manufacturing an endless metal ring for a continuously variable transmission using a transmission belt formed by connecting a plurality of elements by the ring, comprising:
- a bending step of bending a strip into a tubular shape such that both ends of the strip abut on each other;
- a cleaning step of cleaning a first portion to be welded, which is one of the both ends, and a second portion to be welded, which is the other of the both ends, by injecting, with the first portion to be welded and the second portion to be welded abutting on each other, plasma produced from a gas containing oxygen into a groove between the first portion to be welded and the second portion to be welded;
- and
- a welding step of performing welding with the first portion to be welded and the second portion to be welded abutting on each other.
