Tungsten electrodes with their extremely high melting point are used for TIG welding. Although thorium is a radioactive element, which if inhaled represents a risk to the welder, thoriated welding electrodes are still the most commonly used worldwide.

Nevertheless non-radioactive replacement materials for thorium oxide, such as the elements cerium and lanthanum, have proved to be suitable alloying additions for tungsten electrodes.
Thorium-free TIG-welding electrodes such as WC20 and more recently GOLDplus have been further developed for decades at PLANSEE in order to meet market requirements from an ecological point of view.

TIG electrodes from PLANSEE guarantee constant high quality and reproducible results during welding and are available ex-stock in various grades and sizes from PLANSEE EXPRESS.

A special TIG selector is available to help determine the optimum welding parameters.
