Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

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 gas welding skills defined in unit MEM05022C Perform advanced welding using oxy acetylene 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 gas welding of aircraft components or materials

identifying weld requirements from applicable documentation

selecting and correctly using items of PPE applicable to gas welding of aircraft components.

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.
