Modification History
New unit.
Unit Descriptor
This unit of competency covers the development of competency elements required to gain approval within the CASA or ADF regulatory systems to weld aircraft components using the plasma arc welding (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.
Application of the Unit
The unit requires application and adaptation of the skills and knowledge of MEM05044B Perform welds to code standards using gas tungsten arc welding process, to the PAW of applicable aircraft parent metal groups as specified by the Regulators.
Individuals who have attained this unit and the applicable approval from the relevant Regulator for the relevant parent metal groups will be able to perform weld repairs on aircraft components or fabricate components where the applicable welding process is specified as PAW.

Evidence Guide
|
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package. |
|
|
Overview of assessment |
Test pieces must be completed and assessed in accordance with the Regulatory requirements for the granting of aircraft welding approvals. Competency must be separately assessed for each parent metal group for which a PAW authority is sought. |
|
Critical aspects for assessment and evidence required to demonstrate competency in this unit |
Evidence is required of the ability to produce plasma arc welds to required specifications consistently across the range of components that are being fabricated or repaired, while applying all relevant safety precautions. The ability to do this must be demonstrated through the production of the test pieces specified for the welding process and parent metal group in the CAAP 33-1(0) Aircraft manual welding: approvals and qualifications or RAAF Specification Engineering W5003 Welders – Qualification for Aircraft, Missile and Aerospace Fusion welding. |
|
Context of and specific resources for assessment |
Test pieces specified for each parent metal group for which approval is sought may be completed in the workplace or a simulated workplace. The individual must be provided with all required equipment, consumables, PPE, materials and data/drawings relating to the test pieces that are required for the approvals being sought. Assessment of test pieces must be carried out in a testing facility that meets the requirements specified by the applicable Regulator. |
|
Method of assessment |
Assessment methods are specified in the CAAP 33-1(0) Aircraft manual welding: approvals and qualifications or RAAF Specification Engineering W5003 Welders – Qualification for Aircraft, Missile and Aerospace Fusion welding. |
