WebJan 20, 2015 · GTAW, also known as tungsten inert gas (TIG) welding, is a type of arc welding which produces the weld using a non-consumable tungsten electrode. Inert gases such as argon or helium are used to protect the area being welded from contamination and most, although not all, welding applications will require filler metal. WebCommon Tungsten Electrode Grind Angles In manual GTAW, blunter electrodes are generally used in situations where a higher amperage is needed. Thin-walled materials, or other lower amperage tasks where heat effects need to be limited, call for a sharper tungsten grind angle. This thinking informs most tungsten electrode choices for manual …
