Abstract

Welding tongs comprises two electrically conducting arms (10) moving relative to each other with electrode holders (12) on free ends. Holders (12) have welding electrodes (16) touching both sides of sheet flange to be welded during welding. Electrodes (16) each have longitudinal cross-section and longitudinal extension of electrodes (16) run in longitudinal direction of sheet flange to be welded.
