Resistance Welding Electrodes
Electrodes made of pure tungsten, tungsten alloys, molybdenum and electrodes with tungsten or molybdenum inserts. High electrical conductivity with excellent stability at elevated temperatures — significantly longer service life than conventional materials (copper and copper alloys).
Electrode selection by material
- •Uncoated steel → CuCrZr/W
- •Stainless steel → CuCrZr/WCu
- •Coated steel → CuCrZr/Mo/W/WCu
- •Pure copper → Mo/W/WCu
- •Brass (CuZn) / Bronze (CuSn) → CuCrZr/Mo/W/WCu
- •Other copper alloys → CuCrZr/Mo/W/WCu
- •Non-ferrous metals (Al, Mg, Ni, Ti) → CuCrZr/Mo/W/WCu
- •Precious metals (Ag, Au, Pt) → CuCrZr/Mo/W/WCu
- •Refractory metals (Mo, Ta, Cr) → W
