Welding processes and equipment
TIG/WIG
TIG/WIG uses a non-consumable tungsten electrode and an inert shielding gas to produce precise, high-quality welds. The module covers polarity, current type, electrodes, gases, parameters, applications and typical defects.
Open interactive module →Topic overview
TIG/WIG is arc welding with a non-consumable tungsten electrode in an inert gas. Heat is generated by a precise electric arc between electrode and workpiece; filler material may be added separately as a rod or the joint may be welded autogenously.
