This unit applies to the heat treatment of ferrous and non- ferrous metals of various types and thicknesses by a range of methods. These may include oxy acetylene, LPG gas equipment, forge etc. used to heat/quench, temper and anneal materials to specifications.

Work would normally cover one-off processes or processes undertaken as incidental to trade work (e.g. toolmaking, metal spinning etc.)

For more comprehensive or complex heating treatment, Units MEM06003C (Carry out heat treatment) and MEM06004B (Select heat treatment processes and test finished product) should also be considered.

For continuous or batch heat treatment of materials, Unit MEM07024B (Operate and monitor machine/process) should be selected.

3.2. Appropriate heating equipment operating procedures are followed.

3.3. Appropriate equipment adjustments are made.

3.4. Material is treated to achieve required result.

Required skills

Look for evidence that confirms skills in:

reading, interpreting and following information on written job instructions, specifications, standard operating procedures, manufacturer instructions, charts, lists, drawings and other applicable reference documents

checking and clarifying task-related information

following verbal instructions

orally reporting routine information

selecting appropriate processes for heating/quenching, tempering, annealing

setting up, adjusting and operating equipment

Required knowledge

Look for evidence that confirms knowledge of:

characteristics and applications of heating/quenching, tempering, annealing processes

specifications for heating, quenching, tempering, and annealing

process for heating/quenching, tempering, annealing, different materials

operating/adjusting heating equipment

hazards and control measures associated with heating/quenching, tempering, annealing, including housekeeping

use and application of personal protective equipment

safe work practices and procedures

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 basic incidental heat/quenching, tempering and annealing of ferrous and non-ferrous metals by a range of methods, which may include oxy acetylene, LPG gas equipment, forge, and use to heat/quench temper and anneal materials to specifications.

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 heating/quenching, tempering and annealing ferrous and non-ferrous metals 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

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.
