Tungsten electrodes with their extremely high melting point are used for TIG welding. TIG electrodes from PLANSEE guarantee constant high quality and reproducible results during welding.
Characteristics of TIG welding electrodes at a glance.
Electron work function
For perfect ignition and arc stability, the electron work function needs to be as low as possible. This is guaranteed by the oxide doping of tungsten.
Oxide content
A decisive factor for the characteristics of an electrode is the volume percentage of oxide additives. In thorium free qualities this content is higher than in a conventional WT20 electrode.
Oxide distribution
The more homogeneous and fine distributed the oxides are in the structure, the better are the effects on arc stability, ignition, burn-off behavior and service life.
The thorium free qualities WC20 and GOLDplus are characterized by a considerably more homogeneous and finer distribution of oxides.
Burn-off / Service life
Crack-free electrodes as well as a constant electrode tip geometry are required for low burn-off and therefore long service life. Due to perfect precision in the forming process, PLANSEE supplies high quality electrodes without any longitudinal cracks.
Thorium free TIG welding electrodes
The substitute materials cerium and lanthanum have proofed themselves as non-radioactive substitues for thorium oxide. Both materials have an especially low electron work function, which is even lower than that of thorium oxide. Our thorium free TIG-welding electrodes (W, WC20, WL20, GOLDplus) meet requirements concerning ecological and healthrelated aspects.
