DEVICE FOR WELDING THIN SHEETS

摘要

FIELD: welding. SUBSTANCE: device is designed for welding thin sheets transported under fixed water-cooled welding head and can be used for welding longitudinal edges of metal tape formed into tube in shielding gas by means of one or several consumable electrodes 10 arranged in welding head. Each electrode 10 is secured in head by means of electrode chuck 15 in torch body 1 and electrode chuck 5 is held by chuck holder 3 in torch body. Tubular clamping core 7 is placed inside central through hole in chuck holder 3. Electrode 10 is clamped in end of core pointed towards pipe and provided with slots. Thanks to it, electrode 10 can be taken out of chuck holder together with clamping core 7 from top. EFFECT: enlarged operating capabilities. 1 dwg
