Welding electrodes
Resistance welding electrodes in pure tungsten, WLa, WT and WCu, molybdenum, and electrodes with tungsten or molybdenum inserts.
- Why refractory electrodes
- High electrical conductivity and stability at temperature give a much longer service life than copper or copper-alloy electrodes.
- Materials
- Pure tungsten, WLa, WT, WCu, molybdenum and TZM, solid or as inserts in copper bodies.
