Application
This unit of competency defines the skills and knowledge required to prepare and produce welds to code standards using gas metal arc welding (GMAW) on a range of materials.
Butt and fillet welds in the flat, horizontal, vertical and overhead positions would be applied to meet AS 1210-2010 Pressure vessels, AS 4041-2006 (R2016) Pressure piping, and American Society of Engineers (ASME) IX or equivalent.
This unit, in conjunction with Unit MEM05026 Apply welding principles, may satisfy the requirements of AS 1796-2001 (R2016) Certification of welders and welding supervisors Certificate 8G.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
Band: B
