Unit of competency details

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.

• setting welding equipment according to given instructions
• using electric welding machines to weld metal pieces together
• reading and interpreting routine information on written job instructions
• using measuring skills as required
• applying safe working and welding practices
• using and applying personal protective equipment

Required knowledge  

Required knowledge includes:

• basic marking out techniques
• use and care of measuring tools
• behaviour of metals under heat
• welding processes and properties
• post-welding treatments
• safe working and welding practices

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.

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
