List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. | Prepare to perform repair or fabricate test pieces using GTAW process | 1.1 | Materials or components to be welded and the applicable parent metal group are identified in accordance with applicable data |
| | 1.2 | Welding equipment is inspected for serviceability and correctly set up in accordance with standard operating procedures |
| | 1.3 | Component (or materials) is prepared for welding |
2. | Gas tungsten arc weld component | 2.1 | Welds are performed to the required standard in accordance with the applicable repair scheme or drawing while observing all relevant work health and safety (WHS) requirements, including the use of material safety data sheets (MSDS) and items of personal protective equipment (PPE) |
| | 2.2 | Completed welds are inspected for defects and any defects rectified |
3. | Complete documentation | 3.1 | Required documentation is completed in accordance with standard enterprise procedures |
Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria under the specified conditions of assessment, and must include:
safely applying advanced GTAW skills defined in unit MEM05044B Perform welds to code standards using gas tungsten arc welding process, to weld specified aircraft parent metal group materials or components to the standards specified by the relevant Regulator (CASA or the ADF)
applying welding principles (unit MEM05026C Apply welding principles) in the context of welding of aircraft components or materials using the GTAW process
identifying weld requirements from applicable documentation
selecting and correctly using items of PPE applicable to GTAW of aircraft components.
Evidence is required of the ability to produce gas tungsten 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.
Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria and include knowledge of:
regulatory requirements applicable to aircraft welding
standards applicable to aircraft welding
the procedure for assessment of weld test pieces
the use of GTAW in relation to specified aircraft parent metal groups.
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.
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.
Assessors must satisfy the requirements of the National Vocational Education and Training Regulator (Australian Skills Quality Authority, or its successors).
