New unit of competency.

Application

This unit describes the performance outcomes required to carry out advanced gas metal arc welding (GMAW) to replace structural and non-structural vehicle body sections during vehicle body repair work. It involves preparing for the task, selecting and using GMAW equipment, setting gas flow pressures and welder settings, operating gas metal arc welder, selecting and using suitable personal protective equipment (PPE), inspecting and testing weld quality, and completing workplace processes and documentation.

It applies to those working in the automotive service and repair industry.

No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

Elements and Performance Criteria

Elements 

Elements describe the essential outcomes.

Performance Criteria 

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold and italicised text is used, further information is detailed in the range of conditions section.

1. Plan and prepare to carry out advanced GMAW

1.1 Job requirements are determined from workplace instructions

1.2 Welding information  is accessed and interpreted

1.3 Hazards associated with the work are identified and risks are managed

1.4 Tools and equipment  are selected and checked for serviceability

1.5 Work area is prepared and work is planned to carry out GMAW, minimise waste, and use time efficiently

2. Weld using GMAW welder

2.1 GMAW equipment is prepared, set up and adjusted for specific welding job requirement according to manufacturer procedures and safety and environmental requirements 

2.2 Weld test runs are conducted according to workplace instructions and weld specifications

2.3 Materials are welded using standard or inverter GMAW process to industry and original equipment manufacturer (OEM) or authorised agency standards

3. Check welds

3.1 Welds are cleaned using appropriate tools and techniques and according to workplace instructions

3.2 Weld specifications and quality requirements are checked and confirmed by visual inspection and destructive testing

3.3 Weld defects are identified are prepared for re-welding as required, and appropriate personnel are notified

4. Complete work processes

4.1 Final inspection is made to ensure work meets workplace expectations and components are presented ready for use

4.2 Work area is cleaned, waste and non-recyclable materials are disposed of, and recyclable material is collected and stored

Assessment Conditions

Assessors must satisfy NVR/AQTF assessor requirements.

Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting.

Assessment must include direct observation of tasks.

Where assessment of competency includes third-party evidence, individuals must provide evidence that links them to the GMAW that they have carried out, e.g. work orders.

Assessors must verify performance evidence through questioning on skills and knowledge to ensure correct interpretation and application.

The following resources must be made available:

  • automotive repair workplace or simulated workplace
  • workplace instructions
  • GMAW equipment operating instructions
  • PPE required for GMAW
  • body sections specified in the performance evidence requiring GMAW
  • protective screens and fume extraction system
  • standard or inverter GMAW equipment
  • tools, equipment, consumables and materials appropriate for carrying out advanced GMAW.
