Modification History

Release 3 - equivalent. Australian Standard code corrected to AS4041.

Unit Descriptor

This unit covers preparing and producing welds to code standards using flux core arc welding (FCAW).

Application of the Unit

Application of the unit 

This unit applies to the production of butt and fillet welds in all positions. Welds in this unit are associated with high quality fabrications.

Welds produced to the standard of this unit would typically conform to Australian Standard 1210, AS 4041, American Society of Mechanical Engineers (ASME) IX or equivalent. This unit, in conjunction with Unit MEM05026C (Apply welding principles), may satisfy the requirements of AS 1796 Certificate 8F.

Band :

This unit has dual status and is to be regarded as both a Specialisation band A unit and Specialisation band B unit for progression to C7 (AQF level IV).

Unit Weight : 6

Elements and Performance Criteria Pre-Content

Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

Elements and Performance Criteria

ELEMENT 

PERFORMANCE CRITERIA

Required Skills and Knowledge

REQUIRED SKILLS AND KNOWLEDGE 

This section describes the skills and knowledge required for this unit.

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 FCAW
  • using hand and power tools to prepare and weld materials to code standard
  • using measurement and numeracy skills for welding to code standards
  • reading and interpreting routine information on written job instructions, specifications and standard operating procedures. May include drawings

Required knowledge 

Look for evidence that confirms knowledge of:

  • requirements to produce welds to quality of AS1210, AS4041, ASME IX or equivalent
  • safe welding practices
  • use and application of personal protective equipment for FCAW
  • relevant standards or codes
  • methods for preparing plate and pipe for code standard welding
  • pre-welding and post-welding heating methods and requirements for plate and pipe welding to code standard
  • requirements for maintaining weld records to code standard
  • hazards and control measures associated with welding, including housekeeping

Evidence Guide

EVIDENCE GUIDE 

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 prepare and produce welds to code standards using FCAW 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 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 welds to code standards using flux core arc 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, 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 

Range Statement

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 gun, cable, contact tip etc. are in good condition

Prepared 

Flame cut and ground or machined; preheating, setting up of jigs, fixtures, clamps, etc.
