Electrode (1, 21, 41) is designed for welding production and is made of a suspension rod (3, 23, 43) fitted to the edge of parent-plate, and its edges (4, 5, 6; 24, 30, 31; 44, 49, 50) along their edges are supplied with a band (11, 12, 13; 29, 32, 33; 48, 51, 52), made of an insulation material. At least one part of the band is fitted in a groove (7, 25, 45) made in the edge of the electrode. In one of the electrode (4, 5, 6; 24. 30, 31; 44,49, 50) a groove 7, 25, 45) is machined for the band along the edge of electroide (11, 12, 13; 29, 32, 33; 48, 51, 52) machined on insulation material. The front end of the groove fitted at the edge of electrode (4, 5, 6; 24, 30, 31; 44, 49, 50) has a width equal to that of the distant end (10, 28, 53) of the groove machined inside the electrode. 11 claims, 6 figures |
