Look for evidence that confirms knowledge of

regulatory requirements applicable to aircraft welding

standards applicable to aircraft welding

the procedure for assessment of weld test pieces

the use of GMAW in relation to specified aircraft parent metal groups

Look for evidence that confirms skills in

safely applying advanced GMAW skills defined in unit MEMB Perform welds to code standards using gas metal 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

safely applying advanced GMAW skills defined in unit MEM05043B Perform welds to code standards using gas metal 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 MEMC Apply welding principles in the context of welding of aircraft components or materials using the GMAW process

applying welding principles (unit MEM05026C Apply welding principles) in the context of welding of aircraft components or materials using the GMAW process

identifying weld requirements from applicable documentation

selecting and correctly using items of PPE applicable to GMAW of aircraft components

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 GMAW 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 metal 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 Aircraft manual welding approvals and qualifications or RAAF Specification Engineering W 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 datadrawings 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 Aircraft manual welding approvals and qualifications or RAAF Specification Engineering W Welders Qualification for Aircraft Missile and Aerospace Fusion welding
