Gas tungsten arc welding (GTAW), more commonly known as tungsten inert gas (TIG) welding, is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. Itís often a sad fact that beginning TIG welders unintentionally make a lot scrap -- especially when using metals like aluminum. For example, you may feel a need to strike an arc on a piece of aluminum before ever practicing basic hand placement and control. Donít, as this is a waste of good aluminum. The first step to working with aluminum is to master positioning of the torch and hand. But thereís a lot more than that.
Andy Weyenberg, motorsports marketing manager, Miller Electric Mfg. Co., discusses aluminum TIG welding basics. The second step to working with aluminum: coordinating hand movement and filler deposition. To see the first video, jump over here.
