Application
This unit of competency defines the skills and knowledge required to prepare materials and carry out routine gas metal arc welding (GMAW) and applies in a maintenance or manufacturing environment where the weld quality 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 unit MEM05017 Weld using gas metal arc 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 measurement 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.
