TIG Aluminum Welding

Welding is a materials joining process in which localized coalescence (joining) is produced along the faying surfaces of the workpieces. Coalescence is produced either by heating the materials to suitable temperatures, with or without the application of pressure, or it is produced by the application of pressure alone. There are more than 50 different welding processes, classified as either fusion or solid-state (nonfusion) methods. Fusion welding processes, in which the workpieces are melted together at their faying surfaces, are the most commonly used processes, the most common being arc, resistance, and oxyfuel gas welding. In solid-state welding, the workpieces are joined by the application of heat and also usually with pressure. Conventional gas tungsten arc welding (GTAW) is commonly known as tungsten inert gas (TIG) welding. TIG welding is a commonly used high quality welding process and has become a popular choice of welding processes when high quality, precision welding is required. KEYWORDS for this process: gas tungsten arc welding, GTAW
