Unit Descriptor

Unit descriptor	This unit covers assessing task requirements; preparing materials; undertaking the repair, replacement or modification of the fabrication; cleaning and finishing to specifications; and inspecting the result.

Application of the Unit

Application of the unit	This unit requires an integrated level of skills in fabrication maintenance and repair. This unit is intended to build on skills covered by the specialist prerequisites. Processes may involve the simple mark out of materials, and the setting up and operation of a variety of welding and cutting plant/equipment. If individual skills are required, relevant specialist units only should be selected. Where additional or more complex marking out skills are required, refer to Unit MEM12007D (Mark off/out structural fabrications and shapes). If machines and equipment for forming, bending or shaping are required, Unit MEM05010C (Apply fabrication, forming and shaping techniques) should also be selected. Band: A Unit Weight: 4

Elements and Performance Criteria Pre-Content

Elements describe the essential outcomes of a unit of competency.	Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

Elements and Performance Criteria

ELEMENT	PERFORMANCE CRITERIA
1. Assess and process repair, replacement, modification requirement	1.1. Work requirements are determined from job sheet, instruction or visual inspection. 1.2. Specifications and drawings are obtained and interpreted where required. 1.3. Fabrication is inspected and suitability for repair/replacement/modification determined.
2. Assess and process material requirements	2.1. Material requirements are assessed in accordance with relevant codes, manufacturers' specifications and standard operating procedures. 2.2. Materials are obtained/requisitioned according to standard operating procedures. 2.3. Tool and equipment requirements are assessed and obtained, where required, according to standard operating procedures.
3. Prepare materials	3.1. Fabrication for repair/replacement and/or modification is prepared to specification using acceptable workplace practices, tools and equipment. 3.2. Materials are marked out and prepared to specifications with minimum wastage using correct principles, tools, equipment and procedures. 3.3. Materials are cut, bent, rolled, shaped or formed to specifications using appropriate fabrication techniques/procedures, tools and equipment. 3.4. Where required, items are marked for identification.
4. Repair, replace or modify fabrication	4.1. Using suitable clamping methods, equipment, jigs and fixtures, materials are positioned/clamped for welding. 4.2. Pre-tack checks are undertaken and compliance with specifications is determined prior to tack welding in position. 4.3. Welding equipment is prepared and settings are adjusted according to requirements. 4.4. Immediate work site environment is checked to ensure compliance with safety requirements and procedures. 4.5. Material or item is tack welded using appropriate distortion minimisation techniques and procedures. 4.6. Material or item is checked against specifications prior to welding. 4.7. Material or item is welded to specifications using techniques and procedures appropriate to job requirements.

Evidence Guide

EVIDENCE GUIDE
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 repair/replace/modify 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, supervisor's 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.
Guidance information for assessment
