Ceramic pin electrodes used in projection welding of nuts and bolts, providing electrical isolation between the fastener and the workpiece. Manufactured from high-performance ceramic materials including ZrO2, Si3N4 and Al2O3 to withstand temperatures up to 1,000°C.
Ceramic pins prevent current leakage through the fastener thread during nut and bolt projection welding, ensuring the current flows only through the projection contact points. This results in consistent and high-quality welds. Custom dimensions and geometries are available to match specific electrode holder designs.
