Application
This unit of competency defines the skills and knowledge required to prepare materials and perform routine oxy fuel gas welding of mild/low carbon steel and cast iron where the welding is not required to meet an Australian Standard or equivalent.
Where welding is required to meet AS 1554 General Purpose or equivalent codes, work health and safety (WHS) regulations and/or licensing requirements MEM05055 Weld using oxy fuel gas welding process should also be selected.
Where the interpretation of technical drawings is required unit MEM09002 Interpret technical drawing should also be selected.
Where the selection and use of engineering measuring equipment is required unit MEM12023 Perform engineering measurements should also be selected.
Where the selection and use of tools is required unit MEM18001 Use hand tools and unit MEM18002 Use power tools/hand held operations should also be selected as appropriate.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
