Description
This unit of competency covers the development of competency elements required to gain approval within the CASA or ADF regulatory systems to gas weld aircraft components. 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.
Notes
Elements and Performance Criteria
1 Prepare to perform repair or fabricate component using gas welding process
- 1.1 Materials or components to be welded and the applicable parent metal group are identified in accordance with applicable data
- 1.2 Correct welding equipment and consumables are selected and safely set up in accordance with standard operating procedures
- 1.3 Component (or materials) for welding are prepared
- 1.4 Equipment is adjusted ready for the welding process
2 Gas weld component
- 2.1 Welds are performed to the required standard in accordance with the applicable repair scheme or drawing
- 2.2 Completed welds are inspected for defects and any defects rectified
3 Complete documentation
- 2.3 Required documentation is completed in accordance with standard enterprise procedures
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Materials
Materials may be any metal used in the construction of aircraft components that is suitable for gas welding
Component
Component may be any aircraft component where gas welding is specified as either a fabrication or repair technique
Parent metal group
Parent metal groups against which welding authorities are individually granted are:
aluminium alloys
magnesium alloys
carbon steels and low alloy steels
corrosion and heat resisting steels
nickel alloys
copper-based alloys
titanium alloys
Welding equipment
Welding equipment may include:
fuel gases, cylinders, regulators, hoses, torches and tips
Consumables
Consumables may include:
filler rods and fluxes as specified for the task
Required standard
Standards may be specified in:
regulations relating to required test pieces
process specifications
repair manuals
overhaul manuals
Australian and New Zealand Standards

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 gas welding authority is sought.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
Evidence is required of the ability to produce gas 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.
