Modification History

New unit - Release 1

Unit Descriptor

The unit of competency covers the use of manual metal arc, gas metal arc and gas tungsten arc welding machines depending on their availability in the learning institution.

The welding is not required to meet any Australian Standard. Fillet and butt welds would typically be performed on low carbon/mild steels and aluminium if required. The basic settings for the welding machine and the welding materials will be supplied to the learner.

Application of the Unit

This unit is designed for use in a pre-employment skills introduction program and is suitable for use in institutional-based vocational programs. Skills development will take place under direct supervision.

This unit is not to be used in a traineeship or apprenticeship training program or associated qualifications. It is only to be used in pre-employment programs and carries no credit towards apprenticeship/trade and other qualification types in manufacturing and engineering.

This unit should be integrated with the work in the project unit, MEMPE006A Undertake a basic engineering project, and skills developed when required by the project.

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 welding materials and equipment and weld metal materials.

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

Assessors must be satisfied that the candidate can:

  • work safely
  • prepare materials
  • set welding equipment according to given instructions
  • use electric welding machines to weld metal pieces together
  • read and interpret routine information on written job instructions
  • use measuring equipment as required
  • clean and store equipment as instructed.

Context of and specific resources for assessment 

  • This unit must be assessed in a learning institution.
  • Assessment must cover the successful use of one or more electric welding machines.
  • The skills covered by this unit would be demonstrated by an individual working alone under direct supervision.
  • The assessment environment should not disadvantage the candidate.
  • This unit may be assessed in conjunction with any other units addressing the safety, quality, communication, hand tools, machine operation, recording and reporting associated with using electric welding machines.

Method of assessment 

  • Assessment must satisfy the endorsed Assessment Guidelines of the MEM05 Metal and Engineering Training Package.
  • Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure correct interpretation and application.
  • Assessment must confirm a reasonable inference that competency is not only able to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.
  • Assessment should be in conjunction with assessment of the project unit and other units integrated into the project.

Guidance information for assessment 

Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.

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.

Weld requirements 

Weld requirements may be identified from, but are not limited to:

  • drawings
  • sketches
  • job instructions
  • schematics
  • diagrams
  • technical manuals

Type of welding 

Welding involves the use of electric welding machines and may include any or all of the following welding processes:

  • manual metal arc welding
  • gas metal arc welding
  • tungsten metal arc welding
