Application

This unit of competency has been developed for engineering fabrication trade training and the recognition of trade skills in advanced welding using oxy acetylene welding.

It defines the skills and knowledge required to plan, prepare for, and carry out advanced welding using oxy acetylene welding as defined in the unit, in combination with its prerequisites. The required welding may be specified in a relevant Australian or international standard or code and/or in a relevant welding procedure specification (WPS).

Where the welding associated with this unit also requires advanced manual thermal cutting, gouging and shaping, the unit MEM05071 Perform advanced manual thermal cutting, gouging and shaping must also be selected. Where the welding associated with this unit also requires the application of welding to codes and standards, the unit MEM05062 Apply welding and welding related codes and standards must be selected. Where the welding associated with this unit also requires the welding to be undertaken according to a formal WPS, the unit MEM05068 Apply weld procedure specifications must also be selected. Where formal weld records associated with the application of this unit are required to be maintained, the unit MEM05065 Maintain weld records must also be selected.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

Band: A

Unit Weight: 4

  • 5.3 Complete weld records in accordance with SOPs

Assessment Requirements

Performance Evidence

Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include the ability to:

follow work instructions, standard operating procedures (SOPs) and safe work practices

identify and interpret specifications from drawings, sketches and verbal or written job instructions for performing advanced welding using oxy acetylene welding process on at least two occasions

select appropriate weld and joint preparation methods

clean and prepare materials for welding

weld materials in all positions, including fillet and butt in the horizontal, vertical and overhead positions to the specified standard or equivalent on at least two occasions

apply distortion prevention techniques

rectify identified cracks or defects.

Note: Where a volume and/or frequency is not specified, demonstration must be provided at least once.

Knowledge Evidence

Evidence required to demonstrate the required knowledge for this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include knowledge of:

safe welding practices and procedures and use of personal protective equipment (PPE)

purpose of pre-welding and/or post-welding heating and the methods of application

instructions, symbols, specifications, including bead size, bead placement, reinforcement and weld procedure sheet

weld specifications and requirements

causes of weld cracks or defects and methods of rectification

properties and characteristics of materials and consumables used in oxy acetylene welding

fuel gas properties and applications

weld specifications and requirements

different welder identification systems, including numbering, bar coding, paint coding and letter stamps.

Assessment Conditions

Assessors must:

have vocational competency in performing advanced welding using oxy acetylene welding process at least to the level being assessed with relevant industry knowledge and experience

satisfy the assessor requirements in the Standards for Registered Training Organisations 2015 or its replacement and comply with the National Vocational Education and Training Regulator Act 2011, its replacement or equivalent legislation covering VET regulation in a non-referring state/territory as the case requires.

Assessment must occur in a functioning workplace. Where assessment in the workplace would be unsafe, impractical or threatens the environment, assessment must occur in a sufficiently rigorous simulated environment that reflects the circumstances that would be experienced in a functioning workplace. Assessment must cover all aspects of workplace performance, including task skills, task management skills, contingency management skills and job role environment skills

Knowledge assessment may be either verbal or written but must adequately reflect the knowledge requirements of the unit in a functioning workplace.

Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications.

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.

Foundation Skills
