Application

This unit has been primarily developed for Engineering Tradesperson - Fabrication apprenticeship training and the recognition of trade-level skills in oxy fuel gas welding on heavy or light metal fabrications. It may also apply to other trade occupations requiring higher level oxy fuel gas welding skills.

Weld quality must conform to AS 1554 General Purpose (GP) and American Bureau of Shipping (ABS) or equivalent.

Where manual thermal processes associated with preparation, pre-heat and/or post-heat is required, the unit MEM05007 Perform manual heating and thermal cutting and the unit the MEM05071 Perform advanced manual thermal cutting, gouging and shaping, must also be selected as appropriate.

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

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 on at least two occasions and include:

following work instructions, standard operating procedures and safe work practices

identifying and interpreting specifications from drawings, sketches and verbal or written job instructions for oxy fuel gas to AS 1554 General Purpose (GP) or equivalent

selecting appropriate weld and joint preparation methods

setting up:

gas cylinders

hoses

blowpipes

tips and nozzles

regulators

flashback arrestors

weld materials to AS 1554 GP or equivalent using oxy fuel gas welding equipment while preventing distortion

rectifying any defects

completing weld records related to oxy fuel gas onto standard workplace forms.

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 and setting up requirements of:

gas cylinders

hoses

blowpipes

tips and nozzles

regulators

flashback arrestors

material preparation for oxy fuel gas welding

weld joint preparations

filler rod materials

causes of distortion for materials when welded

causes of weld defects and methods of rectification

standards for oxy fuel gas welding, including AS 1554 GP or equivalent.

Assessment Conditions

Assessors must:

have vocational competency in oxy fuel gas welding 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.

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
