Application

This unit of competency has been developed for post trade engineering fabrication training and the recognition of post trade skills in performing welds to code standards using oxy fuel welding.

It defines the skills and knowledge required to prepare and produce welds to code standards using oxy fuel gas welding on different types of materials. Welds covered by this unit include butt and fillet welds in the flat, horizontal, vertical and overhead positions to meet AS 1210 Pressure vessels, AS 4041 Pressure piping and American Society of Mechanical Engineers (ASME) IX or equivalent national or international standards.

This unit, together with units MEM05061 Apply basic metallurgy principles to welding applications, MEM05062 Apply welding and welding related codes and standards and MEM05068 Apply weld procedure specifications may satisfy the requirements of AS 1796 Certification of welders and welding supervisors or equivalent national and international standards.

Where the welding associated with this unit also requires advanced manual thermal cutting, gouging and shaping is required, the Unit MEM05071 Perform advanced manual thermal cutting, gouging and shaping must also be selected.

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

What You'll Learn

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 job specifications and weld parameters from drawings, weld procedure specifications, sketches and verbal or written job instructions for performing welds using oxy fuel gas welding to code standards

clean and prepare materials for welding to specifications on at least two occasions

set up welding equipment and perform routine maintenance

produce butt and fillet welds in the flat, horizontal, vertical and overhead positions to meet customer specifications and the requirements of AS 1210 Pressure vessels, AS 4041 Pressure piping and American Society of Engineers (ASME) IX or equivalent national or international standards on at least two occasions

rectify identified weld discontinuities on at least two occasions

complete and maintain weld records related to oxy fuel gas welding to code standards onto standard workplace forms.

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)

requirements to produce welds to quality of AS 1210 Pressure vessels, AS 4041 Pressure piping and ASME IX or equivalent

AS 1796 Certification of welders and welding supervisors or equivalent national and international standards relevant to oxy fuel gas welding

standards or codes relevant to oxy fuel gas welding

causes and control of distortion when welding to code standards

purpose of and setting up requirements of:

gas cylinders

hoses

blowpipes

tips and nozzles

regulators

flashback arrestors

methods for preparing plate for code standard welding

causes of weld defects and methods of rectification

pre-welding and post-welding heating methods and requirements for plate welding to code standard

requirements for maintaining weld records to code standard.

Assessment Conditions

Assessors must:

have vocational competency in performing welds to code standards using oxy fuel gas 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.
