Elements and Performance Criteria

The range statement provides information about the context in which the unit of competency is carried out. The variables and scope cater for different work requirements, work practices and knowledge between States, Territories and the Commonwealth, and between organisations and workplaces. The range statement relates to the unit as a whole and provides a focus for assessment. Text in italics in the performance criteria is explained here.
The following variables may be present and may include, but are not limited to, the examples listed under the scope. All work is undertaken to relevant legislative requirements, where applicable
Variable
Scope
Distortion prevention/control techniques
Jigs, fixtures, heat, clamps, etc.
Components
General fabricated components in either plate, pipe and section or sheet
Alignment
Typical structural alignment and levelling using planes and line straight edges, spirit levels, line levels, squares, etc.
Fixing/joining techniques
Welding, adhesives, fasteners, rivets, etc.
Codes/standards
All work carried out in accordance with legislative and regulatory requirements

The evidence guide specifies the evidence required to demonstrate achievement in the unit of competency as a whole. It must be read in conjunction with the unit descriptor, performance criteria, range statement and the assessment guidelines for the Metal and Engineering Training Package
Overview of assessment requirements
A person who demonstrates competency in this unit must be able to assemble general fabricated components in plate, pipe and section or sheet. During assessment the individual will: demonstrate safe working practices at all times; communicate information about processes, events or tasks being undertaken to ensure a safe and efficient working environment; take responsibility for the quality of their own work; plan tasks in all situations and review task requirements as appropriate; perform all tasks in accordance with standard operating procedures; perform all tasks to specification; and use accepted engineering techniques, practices, processes and workplace procedures. Tasks involved will be completed within reasonable timeframes relating to typical workplace activities.
Competency in this unit cannot be claimed until all prerequisites have been satisfied.
Context of 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.
Interdependent assessment
This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with the assembly of fabricated components 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.
Consistency of performance
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.
Required skills
Look for evidence that confirms skills in:

constructing jigs where appropriate
applying distortion prevention/control techniques
positioning components in accordance with drawing/specifications
using jigs, fixtures, tools and equipment
correctly marking the datum line
checking the position of all assembled components visually and dimensionally
using appropriate fixing/joining techniques
Required knowledge
Look for evidence that confirms knowledge of:
methods for assembly of fabricated components
jigs construction
effects of distortion of fabricated components
distortion prevention techniques
drawing and material list
characteristics of relevant tools and equipment squareness, level, alignment
function of datum lines
variety of fixing/joining techniques
defects associated with the assembly of fabricated components
methods of rectification of defects by rework or adjustment
requirements of relevant codes/standards
