This unit of competency defines the skills and knowledge required to carry out advanced welding using gas tungsten arc welding (GTAW).

Welds are associated with a range of structural sections and/or plate and/or pipe for general fabrication. Weld quality would typically conform to AS 1554 Structural Purpose or equivalent.

No licensing, legislative or certification requirements apply to this unit at the time of publication.
