MEM05093 Weld using submerged arc welding process

Modification History

Release 1. Supersedes and is equivalent to MEM05023 Weld using submerged arc welding process.

Application

This unit of competency defines the skills and knowledge required to carry out submerged arc welding (SAW) where the welds are more likely to be associated with heavy rather than with light fabrication.

Weld quality must conform to AS 1554 General Purpose (GP) or equivalent.

Where the interpretation of technical drawings is required unit MEM09002 Interpret technical drawing should also be selected.

Where the selection and use of tools is required, the unit MEM18001 Use hand tools and the unit MEM18002 Use power tools/hand held operations, must also be selected as appropriate.

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