Unit of Competency MEA433A - Weld aircraft components using the gas metal arc welding process
Description 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 gas metal arc welding (GMAW) 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.
Employability Skills This unit contains employability skills.
Learning Outcomes and Application The unit requires application of the skills and knowledge of MEM05043B Perform welds to code standards using gas metal arc welding process, to the welding 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 GMAW.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.
Prerequisites/co-requisites MEA101B Interpret occupational health and safety practices in aviation maintenanceMEA105C Apply quality standards applicable to aviation maintenance processesMEA107B Interpret and use aviation maintenance industry manuals and specificationsMEA108B Complete aviation maintenance industry documentationMEM05043B Perform welds to code standards using gas metal arc welding processMEM05026C Apply welding principles

Evidence Required

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.

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 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.

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

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 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 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 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 GMAW

Component

Component may be any aircraft component where GMAW 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

Required standard

Standards may be specified in:

regulations relating to required test pieces

process specifications

repair manuals

overhaul manuals

Australian and New Zealand Standards

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
