MEM05045
Perform pipe welds to code standards using manual metal arc welding process


Application

This unit of competency defines the skills and knowledge required to prepare and produce pipe welds to code standards using manual metal arc welding (MMAW) on a range of materials.

Butt welds in pipe with the axis horizontal, vertical and/or askew would be applied to meet AS 1210-2010 Pressure vessels, AS 4041-2006 (R2016) Pressure piping, and American Society of Mechanical Engineers (ASME) IX or equivalent. The unit, together with unit MEM05026 Apply welding principles, may satisfy the requirements of AS 1796-2001 (R2016) Certification of welders and welding supervisors, Certificates 2 and 4.

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.
