Elements and Performance Criteria

1. Assess and process repair, replacement, modification requirement
   • Work requirements are determined from job sheet, instruction or visual inspection.
   • Specifications and drawings are obtained and interpreted where required.
   • Fabrication is inspected and suitability for repair/replacement/modification determined.
2. Assess and process material requirements
   • Material requirements are assessed in accordance with relevant codes, manufacturers' specifications and standard operating procedures.
   • Materials are obtained/requisitioned according to standard operating procedures.
   • Tool and equipment requirements are assessed and obtained, where required, according to standard operating procedures.
3. Prepare materials
   • Fabrication for repair/replacement and/or modification is prepared to specification using acceptable workplace practices, tools and equipment.
   • Materials are marked out and prepared to specifications with minimum wastage using correct principles, tools, equipment and procedures.
   • Materials are cut, bent, rolled, shaped or formed to specifications using appropriate fabrication techniques/procedures, tools and equipment.
   • Where required, items are marked for identification.
4. Repair, replace or modify fabrication
   • Using suitable clamping methods, equipment, jigs and fixtures, materials are positioned/clamped for welding.
   • Pre-tack checks are undertaken and compliance with specifications is determined prior to tack welding in position.
   • Welding equipment is prepared and settings are adjusted according to requirements.
   • Immediate work site environment is checked to ensure compliance with safety requirements and procedures.
   • Material or item is tack welded using appropriate distortion minimisation techniques and procedures.
   • Material or item is checked against specifications prior to welding.
   • Material or item is welded to specifications using techniques and procedures appropriate to job requirements.
5. Finish and inspect repair, replacements and/or modification
   • Repair, replacement and/or modification is cleaned and finished to specifications using appropriate workplace practices.
   • Welds are visually inspected to assess weld quality against predetermined specifications.
   • Completed repair, replacement and/or modification is assessed against specifications.
   • Maintenance report is prepared and lodged according to standard operating procedures.

Evidence Required

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package
Overview of assessment	A person who demonstrates competency in this unit must be able to integrate skills in fabrication maintenance and repairreplacemodify fabrications Competency in this unit cannot be claimed until all prerequisites have been satisfied
Critical aspects for assessment and evidence required to demonstrate competency in this unit	Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria including required knowledge and be capable of applying the competency in new and different situations and contexts
Context of and specific resources for assessment	This unit may be assessed on the job off the job or a combination of both on and off the job Where assessment occurs off the job that is the candidate is not in productive work then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team The assessment environment should not disadvantage the candidate This unit could be assessed in conjunction with any other units addressing the safety quality communication materials handling recording and reporting associated with repairing replacing or modifying fabrications or other units requiring the exercise of the skills and knowledge covered by this unit
Method of assessment	Assessors should gather a range of evidence that is valid sufficient current and authentic Evidence can be gathered through a variety of ways including direct observation supervisors reports project work samples and questioning Questioning techniques should not require language literacy and numeracy skills beyond those required in this unit of competency The candidate must have access to all tools equipment materials and documentation required The candidate must be permitted to refer to any relevant workplace procedures product and manufacturing specifications codes standards manuals and reference materials

Range Statement

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Fabrication inspected	Determine defects/faults, non-compliance with specifications, repair/replacement/modification
Marked out	Marking out principles, techniques
Marked for identification	To undergo repair, replacement and/or modification, to be cut, bent, rolled, shaped or formed to specifications
Clamping methods	Automatic, semi-automatic, manual methods
Welding equipment	MMAW, GMAW, GTAW
