Elements and Performance Criteria

1. Maintain welding equipment
   • Routine maintenance is performed on welding equipment.
2. Prepare welding materials and equipment for MMAW pipe welding to code standards
   • Weld requirements for MMAW welding to code standards are determined.
   • Welding equipment is set up correctly.
   • Materials are prepared to produce pipe weld to code standard.
3. Weld pipe using MMAW to procedure specifications
   • Materials are welded as per weld procedure specification.
4. Ensure weld quality
   • Discontinuities are rectified to ensure conformance to code requirements.
   • Weld records are maintained in accordance with standard operating procedures.

Required Skills

Required skills

Look for evidence that confirms skills in depositing welds to procedure requirements determining weld outcomes consumables and settings from welding procedure specification interpreting technical drawings and weld specifications for welding to code standards using MMAW using hand and power tools to prepare and weld materials to code standard using measurement and numeracy skills for welding to code standards using language and literacy skills to enable completion of weld records

Required knowledge

Look for evidence that confirms knowledge of requirements to produce welds to quality of AS AS ASME IX or equivalent safe welding practices use and application of personal protective equipment for MMAW knowledge of appropriate standards or codes methods for preparing pipe for code standard welding prewelding and postwelding heating methods and requirements for pipe welding to code standard requirements for maintaining weld records to code standard hazards and control measures associated with welding including housekeeping

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 pipe welds to code standards using MMAW process 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 Where assessment occurs off the job ie the candidate is not in productive work 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 the preparation and production of welds 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.
Routine maintenance	Ensuring leads, hand pieces etc. are in serviceable condition, and correct current carrying capacity
Prepare welding materials	Preheating, setting up of jigs, fixtures, clamps, etc.
Prepared	Flame cut and ground or machined
Materials	Carbon/manganese steel, stainless steel and low alloy steel materials, etc.
