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

Required skills

Look for evidence that confirms skills in:

visually inspecting fabrication for defects, faults, and compliance

marking out

minimising wastage of materials

cutting, bending, rolling, shaping or forming materials

positioning and clamping materials for welding

undertaking pre-welding/tacking checks

setting up and adjusting welding equipment

tack welding

welding according to all relevant codes, and specifications

cleaning and finishing materials/fabrication

reading and interpreting job sheets, specifications, drawings, standard operating procedures, manufacturer documentation and other literature to the level required by this unit

assessing material and equipment requirements

using measuring skills for preparing and marking out materials and for checking modification against specifications

completing short reports using relevant terminology and format

Required knowledge

Look for evidence that confirms knowledge of:

applicable industry standards, national/Australian standards, NOHSC guidelines, State/Territory regulatory codes of practice/standards

characteristics of faults, defects and or non-compliance

means of rectifying faults, defects and/or non-compliance by rework or additional work, or by replacement of components/materials

effects of proposed modifications on the fabrication

reasons for selection of specific materials, tools, equipment and consumables

marking out principles, techniques

material preparation processes

clamping method(s) for the welds undertaken.

location of all materials to be welded

weld specifications

equipment, consumables and settings required to achieve the weld specification

distortion minimisation procedures and methods for rectifying any distortion of materials

material cleaning and finishing processes for the repair/replacement/modification

reporting requirements

use and application of personal protective equipment

safe work practices and procedures

hazards and hazard control measures associated with repairing, replacing or modifying fabrications

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
