TIG WELDING
TUNGSTEN ELECTRODES
TUNGSTEN ELECTRODES
Tungsten electrodes are used in arc welding with inert gas and tungsten (TIG). Tungsten is used at very high temperatures as it resists melting and degrades very little (if working in a controlled atmosphere with inert gases as is usually the case). The electrodes are made by sintering powders and subsequent forging.
Tungsten electrodes for TIG generally contain small quantities of metal oxides which ensure benefits of materials such as:
• Facilitated start of the current transient
• Improved arc stability
• Increased current of the rod
• Reduced risk of contaminating the base surface
• Increased life of the electrode
The most used electrodes for the TIG welding process are as follows:
• Pure tungsten electrodes
• Thoriated tungsten electrodes
• Cerium tungsten electrodes
• 1.5% or 2% Lanthanum tungsten electrodes
• Universal tungsten electrodes

THORIATED TUNGSTEN ELECTRODE WT 20
TIG WELDING - TUNGSTEN ELECTRODES - THORIATED TUNGSTEN ELECTRODE WT 20
These electrodes contain 2% thorium and are the most used in the world for their excellent welding performance. Specific for welding stainless steel. They require a good suction system as it’s vapours or dusts are harmful if inhaled, especially when sharpening. Since this material in certain conditions contains radioactive elements, even below the tolerance thresholds allowed, this electrode is only supplied upon request.
