Unit of competency
Modification History
Release 2. Equivalent to MEA434 Weld aircraft components using the plasma arc welding process with amended prerequisite codes.
Application
The unit of competency requires application and adaption of the skills and knowledge of MEM05044B Perform welds to code standards using gas tungsten arc welding process, to the plasma arc welding (PAW) of applicable aircraft parent metal groups as specified by the Regulators during scheduled or unscheduled maintenance. Work may be performed individually or as part of a team.
The unit covers the development of competency elements required to gain approval within the Civil Aviation Safety Authority (CASA) or the Australian Defence Force (ADF) regulatory systems to weld aircraft components using the PAW process. Individuals will be authorised to weld specific parent metal groups, as specified in CAAP 33-1(1) Aircraft manual welding: approvals and qualifications or RAAF Specification Engineering W5003 Welders – Qualification for Aircraft, Missile and Aerospace Fusion welding.
