Gas tungsten arc welding (GTAW, also known as tungsten inert gas welding or TIG, and heliarc welding when helium is used) is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. The weld area and electrode are protected from oxidation or other atmospheric contamination by an inert shielding gas (argon or ...
Orbital welding has almost always exclusively been carried out by the Tungsten Inert Gas (TIG / GTAW) technique using non-consumable electrodes, with additional cold-wire feed where necessary. The easy control of heat input makes TIG-welding the ideal welding method for fully orbital welding of tubes with specialist orbital welding heads, that ...
TIP TIG welding torch. TIP TIG is a subset of gas tungsten arc welding (GTAW), using a mechanism called filler wire agitation to enhance molten weld pool dynamics. This agitation has been found to enhance the weld puddle fluidity and release evolving gases, reducing the chances of inclusions and porosity, and also separate impurities. [1] [2 ...
This wire normally has a thickness of 1.6 mm to 6 mm (1/16 in. to 1/4 in.). In certain circumstances, twisted wire can be used to give the arc an oscillating movement. This helps fuse the toe of the weld to the base metal. [4] The electrode composition depends upon the material being welded. Alloying elements may be added in the electrodes.
(The Center Square) — In Louisiana, violent and property crime numbers across the state have dropped from recent years. Despite this, a survey earlier this year from the Manship School at LSU ...
