Unit of competency

Modification History

Release 1. New Unit.

Application

This unit of competency was developed for engineering fabrication trade training and the recognition of trade skills in applying welding procedure specifications (WPS) to welding and related tasks.

It defines the required welding and material knowledge and skills, relevant welding standards, welding terminology and welder qualification requirements to undertake welding to a WPS as defined in the unit in conjunction with its prerequisites.

This unit must be selected in combination with one or more of the MEM welding process units aligned to AS 1554 General Purpose (GP), or equivalent. Higher level MEM welding process units may also be used for the co-assessment. MEM AS 1554 GP or equivalent aligned units are:

MEM05090 Weld using manual metal arc welding process

MEM05091 Weld using gas metal arc welding process

MEM05092 Weld using gas tungsten arc welding process

MEM05097 Weld using oxy fuel gas welding process

MEM05093 Weld using submerged arc welding process

MEM05096 Weld using flux core arc welding process.

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

Assessment requirements

Modification History

Release 1. New Unit.

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:

• review approved weld procedure specifications (WPS) for at least three fabrication designs requiring welding to at least AS1554 General Purpose (GP) or equivalent including:

• comparing WPS requirements to design requirements and enterprise procedures
• identifying required welding parameters
• identifying sampling and test requirements

• use procedures for seeking clarifications and variations to approved WPS
• produce at least three test pieces consistent with different WPS
• perform fit up, joint preparation and welding including any required pre and/or post weld heating for at least two fabrication designs and their approved WPS.

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:

• welding symbols and abbreviations used in Australian or equivalent international standards
• welding parameters
• typical methods to store and access current copies of WPS in an enterprise
• standard WPS formats and content headings
• procedures for production of test pieces for destructive and non-destructive tests (NDTs)
• types of welding related NDTs and their application
• procedures for:

• verifying/amending previously established weld test procedures
• completing welding against a WPS

• welding parameters included in WPS and how they vary depending on the specified welding process.

Assessment Conditions

• Assessors must:

• have vocational competency in developing and maintaining welding procedures 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 replacementand comply with the National Vocational Education and Training Regulator Act 2011, its replacementor 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.
