Unit of competency
Modification History
Release 1. Unit code changed. Changes to prerequisites, elements and performance criteria, performance evidence and knowledge evidence. Supersedes and is not equivalent to MEM05046 Perform welds to code standards using manual metal arc welding process.
Application
This unit of competency has been developed for post trade engineering fabrication training and the recognition of post trade skills in performing welds to code standards using manual metal arc welding.
It defines the skills and knowledge required to prepare and produce welds to code standards using manual metal arc welding (MMAW) on different types of materials. Welds covered by this unit include butt and fillet welds in the flat, horizontal, vertical and overhead positions to meet the requirements of AS 1210 Pressure vessels, AS 4041 Pressure piping, and American Society of Mechanical Engineers (ASME) IX or equivalent national and international standards
This unit, together with units MEM05061 Apply basic metallurgy principles to welding applications, MEM05062 Apply welding and welding related codes and standards and MEM05068 Apply welding procedure specifications, may satisfy the requirements of AS 1796 Certification of welders and welding supervisors or equivalent national and international standards.
Where the welding associated with this unit also requires advanced manual thermal cutting, gouging and shaping, the unit MEM05071 Perform advanced manual thermal cutting, gouging and shaping must also be selected.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
