Application
This unit describes the performance outcomes required to prepare and weld components using the manual metal arc welding (MMAW) process. It involves preparing for the task, selecting, setting up and operating MMAW equipment, identifying and selecting welding electrodes appropriate to welding requirements, selecting and using suitable personal protective equipment (PPE), performing welding to required standard and specifications, inspecting 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.

2.3 Test runs are conducted according to workplace instructions and quality requirements
2.4 Materials are welded using MMAW process to required specifications
|
|
3. Check welds
|
3.1 Weld quality and specifications are confirmed by non-destructive inspection
3.2 Weld defects are identified, 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 component is 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
4.3 Tools and equipment are checked, reported if faulty, and stored according to workplace procedures
4.4 Workplace documentation is processed according to workplace procedures
|

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 MMAW 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
- PPE required for MMAW
- components to be welded as specified in the performance evidence
- welding materials and consumables
- MMAW equipment and operating instructions
- tools, equipment and materials appropriate for carrying out MMAW.
