摘要：PROBLEM TO BE SOLVED: To provide a method for shaping an electrode in a seam welding machine where the occurrence of hunting is prevented, a disk-shaped electrode is always shaped into a completely round state by a shaping roller, and welding quality can be secured, and to provide a device therefor. SOLUTION: The method for shaping an electrode in a seam welding machine comprises: a first process where a shaping roller 12 is pressed against a disk-shaped electrode 11 by a pressing mechanism 13 using a pneumatic cylinder 25; and a second process where the locking of the pneumatic cylinder 25 is performed using a locking mechanism 14, and in a state where the position of the shaping roller 12 abutted against a disk-shaped electrode 11 is held, dressing for the disk-shaped electrode 11 is performed, and, during the dressing in the second process, the pressing operation of the shaping roller 12 in the first process is inserted in a short time.
