What an assessment for MEM05081 must cover

31 assessable components: 3 elements (14 performance criteria), 8 performance evidence and 9 knowledge evidence requirements. 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 Determine job requirements

1.1Follow standard operating procedures (SOPs)
1.2Comply with work health and safety (WHS) requirements at all times
1.3Use appropriate personal protective equipment (PPE) in accordance with SOPs
1.4Identify job requirements from weld procedure specifications (WPS), customer requirements, drawings, job sheets or work instructions
1.5Obtain WPS clarification or approval of variation to WPS from appropriate person as required

2 Prepare welding materials and equipment for GTAW welding to code standard

2.1Prepare materials to produce weld to code standard
2.2Perform routine maintenance on welding equipment
2.3Set up welding equipment
2.4Select consumables in accordance with WPS

3 Weld joints using GTAW to procedure specifications

3.1Weld materials in accordance with WPS
3.2Apply post-welding heat treatment where specified
3.3Inspect welded joints visually for conformance to specifications
3.4Rectify discontinuities to ensure compliance to code requirements
3.5Maintain weld records according to SOPs

Performance evidence

follow work instructions, standard operating procedures (SOPs) and safe work practices
identify and interpret job specifications and weld parameters from weld procedure specifications drawings, sketches and verbal or written job instructions for performing pipe welds using manual metal arc welding (MMAW) to code standards on at least two occasions
clean and prepare materials for welding to specifications
set up welding equipment and perform routine maintenance
produce butt welds in pipe with the axis horizontal, vertical and/or askew to meet customer specifications and the requirements of AS 1210 Pressure vessels, AS 4041 Pressure piping, and American Society of Mechanical Engineers (ASME) IX or equivalent national and international standards on at least two occasions
rectify identified weld discontinuities on at least two occasions
complete and maintain weld records related to MMAW to code standards onto standard workplace forms.
Note: Where a volume and/or frequency is not specified, demonstration must be provided at least once.

Knowledge evidence

safe welding practices and procedures and use of personal protective equipment (PPE)
requirements to produce welds to quality of AS 1210 Pressure vessels, AS 4041 Pressure piping, and ASME IX or equivalent
AS 1796 Certification of welders and welding supervisors or equivalent national and international standards relevant to MMAW
standards or codes relevant to performing pipe welds to code standards using MMAW
methods for preparing pipe for code standard welding
pre-welding and post-welding heating methods and requirements for pipe welding to code standard
causes and control of distortion when welding to code standards
welding cracks or defects relevant to MMAW pipe welding to code standards
requirements for maintaining weld records to code standard.

Questions about assessing MEM05081

What does an assessment tool for MEM05081 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEM05081 needs to address all 31 unit components: 3 elements with 14 performance criteria, 8 performance evidence requirements, 9 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 MEM05081?

Auditori pulls the current release of MEM05081 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 MEM05081 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MEM05081 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 MEM05081, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
