Application

This unit of competency has been developed for post trade engineering fabrication training and the recognition of post trade skills in welding inspection.

It defines the skills and knowledge required to perform welding inspections, organise appropriate non-destructive tests (NDTs), validate welding procedure specifications (WPS), ensuring that quality assurance is carried out and monitoring procedures are undertaken, as defined in the unit in conjunction with its prerequisites.

Competency in this unit is based on broad knowledge of metallurgy associated with welding, mechanical properties of welded joints, heat treatment procedures and national and international welding and related standards. Test procedures and the scope of this unit of competency are determined by applicable Australian and/or international standards.

Where the conduct of destructive and/or non-destructive testing is required the appropriate test units must also be selected.

This unit must be selected in combination with one of the MEM coded welding units and their prerequisites. These units include:

MEM05060 Perform welds to code standards using submerged arc welding process

MEM05079 Perform welds to code standards using flux core arc welding process

MEM05080 Perform welds to code standards using gas metal arc welding process

MEM05081 Perform welds to code standards using gas tungsten arc welding process

MEM05082 Perform pipe welds to code standards using manual metal arc welding process

MEM05083 Perform welds to code standards using manual metal arc welding process

MEM05088 Perform welds to code standards using oxy fuel gas welding process.

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

review welding requirements for at least two welding projects and determine the scope of welding inspection required

organise appropriate destructive and non-destructive tests or verify results of previous test procedures

identify and validate welding procedures by interpreting joint design specification, organising test pieces, sample plates and pipe, interpreting the results and preparing a report identifying any required actions

ensure quality assurance procedures are carried out, including checking identification (material test certification numbers), and documenting movement of material through workshop or site

check materials can be traced to their source and a traceability register is being maintained

carry out final inspection of fabrications, including material forming and dimensional checks against specifications

maintain and review welding inspection records to ensure compliance on at least two occasions.

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)

welding terminology and symbols

non-destructive testing methods associated with welding and their application

arithmetic operations, formulae and calculations required for testing welding/fabrications

procedures for:

initiating the weld tests and obtaining previous weld tests

verifying/amending previously established weld test procedures

documenting welding procedures and preparing weld test pieces

documenting/recording the movement of material through the workshop and reasons why this is necessary

transferring material test certification numbers

identifying consumables and reasons for marking consumables for identification purposes

using and storing consumables and the consequences of inappropriate use and/or storage of consumables

maintaining welding quality records

reasons for any identified discrepancies between previous and current weld tests

effects of testing procedures on test results

parameters and variables affecting the performance of the weld with respect to specifications

weld discontinuities and relationship to weld quality

tools, equipment, techniques and procedures necessary to check each variable, form and dimensions of the welded components

tools, equipment, techniques and procedures to initiate, carry out, obtain and report the prescribed tests results

discrepancies between the test results and weld specifications and remedial action to be taken to return welds produced to specification

reasons and methods for correctly marking/identifying weld materials

person(s) who can witness the transfer of material test certification numbers and reasons why this is important

storage life of consumables

welding quality requirements of the relevant code, standard and/or welding procedure.

Assessment Conditions

Assessors must:

have vocational competency in performing welding inspection 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.
