Elements and Performance Criteria

1. Select welding equipment and consumables
   • Correct welding equipment and consumables are selected from weld procedure specifications.
2. Prepare welding materials and equipment
   • Welding equipment and consumables are prepared according to job requirements.
   • Welding equipment appropriate to the task is assembled and adjusted correctly and safely.
   • Materials are prepared to achieve required weld specification.
3. Assemble welding equipment
   • Welding equipment, including cylinders, regulators, hoses, torches and tips is assembled and set up safely in accordance with standard operating procedures.
4. Weld joints to Australian Standard 1554 SP or equivalent
   • Materials are welded to Australian Standard 1554 SP or equivalent in all positions.
   • Instructions, symbols, specifications are interpreted correctly including bead size, bead placement, reinforcement etc. and in accordance with weld procedure sheet, if available, and standard operating procedures.
5. Inspect welds
   • Weld joints are visually inspected against specifications.
   • Weld defects are identified.
6. Correct faults
   • Defects are removed with minimum loss of sound metal using correct and appropriate techniques and tools to Australian Standard 3992 or equivalent.
7. Maintain weld records
   • Weld records are maintained in accordance with specifications and standard operating procedures.

Required Skills

Required skills

Look for evidence that confirms skills in selecting equipment and consumables assembling welding equipment welding to AS SP inspecting welds to specification correcting weld faults to AS entering information on to proformas and standard workplace forms using hand and power tools to prepare and weld materials interpreting weld requirements and specificationsprocedures using measurement and numeracy skills for advanced oxy acetylene welding selecting equipment and consumables appropriate to given task using visual identification of defectsfaults

Required knowledge

Look for evidence that confirms knowledge of preparatory requirements the purpose and examples of prewelding and postwelding heating of the weld materials the appropriate settings for the given task and the selected equipmentconsumables the purpose of reinforcing areas to be welded the methods of weld defect removal and their application material and consumable properties and characteristics requirements of ASSP and AS or equivalent fuel gas properties and applications post treatments recording procedures safe welding practices use and application of personal protective equipment for oxy acetylene welding relevant hazards and control measures related to the competency

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 perform advanced oxy acetylene welding carried out using a range of materials for general fabrication 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 performing advanced welding using oxy acetylene welding process 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.
Equipment and consumables	Fuel gases, including acetylene, LPG, hydrogen etc., cylinders, regulators, hoses, torches, tips, range of filler rods and fluxes
Weld	Fillet and butt in the horizontal, vertical and overhead positions
Preparing materials	Preheating, setting up of jigs, fixtures, clamps, etc., joint preparation e.g. bevelling
Materials	Low carbon steel, plate, pipe, tube and round bar
