Description
Employability Skills
Learning Outcomes and 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.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

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.
