Tungsten Electrodes

8 products

TIG (tungsten inert gas) electrodes each insert into a compatible TIG torch that is connected to a TIG welder that supplies current to the electrode. An arc is created between the electrode and the workpiece, and the heat from the arc melts the workpiece material to create the weld. The type of electrode used depends on the base material and thickness of the workpiece, as well as the type of output current provided by the welder. Also known as gas tungsten arc welding (GTAW), TIG welding creates clean, precise welds and is ideal for welding thin materials and surfaces that will be visible. A complete TIG torch setup includes a nozzle, collet body or gas lens, collet, insulators, back cap, torch body, torch handle, and electrode.

Thoriated Tungsten Electrodes

Thoriated Tungsten Electrodes

Thoriated tungsten electrodes are consumed more slowly than other types of TIG electrodes and are the most commonly used type of tungsten electrode. They provide good arc starts and good arc stability for moderate-current AC or DC welding on copper, nickel, titanium, and stainless steel. Thoriated tungsten electrodes contain thorium, which is a radioactive substance. The electrodes insert into a compatible TIG torch that is connected to a TIG welder that supplies current to the electrode.
