AURVTW001 Carry out manual metal arc welding on components
Assessment tool
Version 1.0 Issue Date: May 2024
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.
You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

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.
