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

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

Where advanced manual thermal cutting, gouging and shaping is required unit MEM05008 Perform advanced manual thermal cutting, gouging and shaping should also be selected.

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