Lincoln tig welders

 
Tungsten inert gas (TIG) welding, also known as gas tungsten arc welding (GTA welding or GTAW), is often used in aircraft applications. TIG welding provides a clean, strong weld joint that makes it ideal for assembling and repairing various aircraft components. Lincoln tig welders are superb for your welding needs.

TIG welders and the TIG welding process are capable of producing very high quality welds in almost all metals and alloys. However, TIG welding produces the slowest metal deposition rate of all the arc welding processes and thus would not be used where a high deposition rate is required. TIG welders and the TIG welding process are also especially well suited to welding thin materials where the requirements for quality and finish are exacting. To make the most of the advantages offered by TIG welders and TIG welding, a highly experienced and skilled operator is necessary.
 
In TIG welding, a non-consumable tungsten electrode is used to establish an arc on the base metal. The heat of the arc produced melts the base metal and produces a weld pool. In contrast to normal stick welding, when TIG welding, an inert gas shields the weld area in order to prevent air from contaminating the weld. This shielding gas prevents oxidation of the tungsten electrode, the molten weld puddle, and the heat-affected zone adjacent to the weld bead.

 

In a typical TIG setup, an AC/DC welding machine is used with a flow of shielding gas. The shielding gas goes through a regulator and flow meter and on to the torch. The torch has a collet/collet body combination that holds the electrode. A heat-resistant cup or ceramic nozzle surrounds the electrode and controls the gas shield. In addition, water-cooled TIG machines are available for high-amperage welding applications.
