Welding. A worker practicing using a tungsten inert gas (TIG) welding torch on a piece of aluminium. TIG welding, also known as Gas Tungsten Arc Welding or GTAW, is ideally suited to non-ferrous materials as it uses an non-consumable tungsten electrode often with a filler rod of the same material as the work piece. TIG welding is a highly-skilled process. Photographed at a non-ferrous metal processing plant at Yekaterinberg, Russia.
