What an assessment for AURVTW104 must cover

71 assessable components: 4 elements (15 performance criteria), 2 performance evidence and 48 knowledge evidence requirements, plus 6 foundation skills. An audit-defensible tool maps every question and task back to these — that mapping is the coverage matrix Auditori generates alongside the assessment.

Elements & performance criteria

1 Plan and prepare to weld

  • 1.1Determine job requirements from workplace instructions
  • 1.2Access and interpret welding information
  • 1.3Identify hazards associated with the work and manage risks
  • 1.4Select and check tools and equipment for serviceability
  • 1.5Prepare work area and plan work to carry out TIG welding, minimise waste, and use time efficiently

2 Weld materials using TIG welder

  • 2.1Prepare, set up and adjust TIG welding equipment for specific welding job requirement
  • 2.2Use TIG welding equipment according to manufacturer operating procedures and safety and environmental requirements
  • 2.3Conduct weld test runs according to workplace instructions and weld specifications
  • 2.4Weld materials using standard or inverter TIG process to industry standards

3 Check welds

  • 3.1Clean welds using required tools and techniques and according to workplace instructions
  • 3.2Check and confirm weld specifications and quality requirements by non-destructive inspection
  • 3.3Identify weld defects, prepare for re-welding as required, and notify required personnel

4 Complete work processes

  • 4.1Conduct final inspection according to workplace procedures and confirm vehicle is ready for use
  • 4.2Clear work area and dispose of or recycle materials according to workplace procedures
  • 4.3Process workplace documentation according to workplace procedures

Performance evidence

  • carry out tungsten inert gas (TIG) welding to each of the following material sections: 150 mm long: aluminium, steel, stainless steel
  • in the course of the above work, utilise each of the following weld positions: butt, outside corner, fillet, lap

Knowledge evidence

  • methods to locate and interpret information required to carry out tungsten inert gas welding, including:
  • manufacturer specifications and operating procedures or equivalent documentation
  • national standards and codes of practice for welding
  • workplace procedures required to carry out tungsten inert gas welding, including:
  • establishing serviceability of tools and equipment
  • documentation procedures
  • housekeeping procedures, including:
  • examination of tools and equipment
  • storage of equipment
  • identification, tagging and isolation of faulty equipment
  • disposal of excess materials

  • methods and techniques for TIG welding, including:
  • welding positions:
  • butt
  • outside corner
  • fillet
  • lap
  • weld distortion and distortion control techniques
  • TIG testing procedures, including procedures for visual or non-destructive weld testing
  • procedures for identifying and rectifying weld defects, including:
  • lack of penetration
  • excessive weld build-up
  • excess heat
  • undercut
  • heat affected zone
  • procedures for protecting vehicle electronics during TIG welding
  • procedures for final inspection of welded components

Foundation skills

  • Learning: Locates required sources of information efficiently.
  • Numeracy: Identifies and sets TIG welder settings Identifies weld measurements from job requirements Measures material from specifications.
  • Oral communication: Clarifies instructions and procedures Reports quality issues and job outcomes clearly.
  • Planning and organising: Plans own work requirements Prioritises actions to achieve required outcomes Ensures tasks are completed within workplace timeframes.
  • Problem solving: Identifies defects, quality issues and potential problems associated with TIG welding processes and refers problems to required person.
  • Technology: Uses specialist TIG equipment.

Questions about assessing AURVTW104

What does an assessment tool for AURVTW104 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for AURVTW104 needs to address all 71 unit components: 4 elements with 15 performance criteria, 2 performance evidence requirements, 48 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.

How does Auditori generate an assessment tool for AURVTW104?

Auditori pulls the current release of AURVTW104 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.

Is the first assessment tool really free?

Yes. Every new account includes one free credit — enough to generate the complete assessment tool for AURVTW104 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing AURVTW104 assessment instead of generating a new one?

Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of AURVTW104, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
