Beschreibung
Zusammenfassung:	1,105,636. Welding by pressure. G. CLAAS. 25 Aug., 1966 [28 Aug., 1965], No. 38216/66. Heading B3R. An electrode for electric spot welding comprises an electrically conductive substantially non-metallic insert in a recess open towards the working- face of the electrode, the insert having a lower electrical conductivity than the main body of the electrode. The upper water-cooled electrode 12, Fig. 2, of a machine especially for welding galvanized plates has an insert 15 formed by a graphite lead pencil refill and the lower electrode is identical. Roller electrodes 22, Fig. 4, for spot welding are provided with pin-like inserts 25 or annular inserts. The inserts in one roller may be offset relative to those in the other.
