Elements and Performance Criteria

1. Identify assembly method and construct jigs if required
   • Method is identified and jigs are constructed from engineering drawings or according to workshop practice
   • Distortion prevention/control techniques are correctly applied
2. Ensure all components for assembly are available
   • All components are checked against drawings and material list
3. Select tools and fixtures for fabrication assembly
   • Most appropriate equipment is selected
4. Assemble fabricated components
   • Material and/or fabricated components are correctly positioned
   • Jigs, fixtures, tools and measuring equipment are correctly adjusted and applied
   • Datum line is correctly determined if necessary
   • Assembled components are checked for position including squareness, level and alignment to specification
   • Fixing/joining techniques are applied as necessary according to standard operating procedures
   • Assembly is checked for compliance with drawing
   • Codes/standards are interpreted and applied

Required Skills

Required skills

Required skills include constructing jigs where appropriate applying distortion preventioncontrol techniques positioning components in accordance with drawingspecifications using jigs fixtures tools and equipment correctly marking the datum line checking the position of all assembled components visually and dimensionally using appropriate fixingjoining techniques

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 safely assemble general fabricated components in plate pipe and section or sheet to specifications and drawings using accepted engineering trade techniques practices processes and workplace procedures Competency in this unit cannot be awarded 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 apply the skills covered in this unit of competency in new and different situations and contexts Critical aspects of assessment and evidence include planning assembly tasks and sequences determining and implementing appropriate distortion control techniques assembling general fabricated components in plate pipesection or sheet to specifications codes occupational health and safety OHS regulations and standard operating procedures demonstrating safe working practices at all times ability to assemble components in a workshop and site environment
Context of and specific resources for assessment	This unit has been developed to support training in and recognition of trade level competency in assembly of fabricated components as applied to a sheet metal or metal fabrication environment Assessment should emphasise a workplace context and procedures found in the candidates workplace The competencies covered by this unit can be demonstrated by an individual working alone or as part of a team The assessment environment should not disadvantage the candidate
Method of assessment	Typically persons engaged in Engineering Tradesperson Fabrication work are required to use their fabricated assembly skills and techniques across a range of jobs and specifications A single assessment event is not appropriate On the job assessment should be included as part of the assessment process wherever possible Where assessment occurs off the job judgement must consider evidence of the candidates performance in a productive work environment that includes a sufficient range of appropriate tasks and materials to cover the scope of application for this unit 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
Guidance information for 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 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

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.
Distortion prevention/control techniques	Distortion prevention/control techniques may include: jigs fixtures heat clamps
Components	Components may include general fabricated components in either plate, pipe and section or sheet
Alignment	Alignment may include typical structural alignment and levelling using planes and line straight edges, spirit levels, line levels and squares
Fixing/joining techniques	Fixing/joining techniques may include: welding adhesives fasteners rivets
Codes/standards	All work carried out in accordance with legislative and regulatory requirements
