Abstract

PURPOSE: To effect a stable welding work at all times by a method wherein copying rollers are proceeded and retreated individually by detecting an abnormality on a copied surface by a detecting switch.
CONSTITUTION: A pair of copying rollers 21, 21', being rolled for copying under being abutted against a back surface of a base metal 2 for welding from a direction opposing to a welding torch 3, are provided at a forward and backward positions in a progressing direction of a welding. The respective copying rollers 21, 21' are mounted movably in proceeding and retreating directions in a direction orthogonal to a back surface of the base metal 2 independently with each other and with the welding torch 3. A detecting switch 22 detecting an abnormality on the back surface of the base metal 2 is attached to a position further in front of these copying rollers 21, 21' to proceed and retreat the copying rollers 21, 21' respectively and individually in accordance with a detecting signal thereof, thereby, the abnormality on the back surface of the base metal 2 is not delivered to the torch side 3 directly and a stable copying welding can be effected at all times.
