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 manual metal arc welding.

It defines the skills and knowledge required to prepare and produce welds to code standards using manual metal arc welding (MMAW) 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 the requirements of AS 1210 Pressure vessels, AS 4041 Pressure piping, and American Society of Mechanical Engineers (ASME) IX or equivalent national and 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 welding 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, 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

1. Determine job requirements

  • 1.1 Follow standard operating procedures (SOPs)
  • 1.2 Comply with work health and safety (WHS) requirements at all times
  • 1.3 Use appropriate personal protective equipment (PPE) in accordance with SOPs
  • 1.4 Identify job requirements from weld procedure specifications (WPS), customer requirements, drawings, job sheets or work instructions
  • 1.5 Obtain WPS clarification or approval of variation to WPS from appropriate person in accordance with SOPs

2. Prepare welding materials and equipment for MMAW welding to code standard

  • 2.1 Prepare materials to produce weld to code standard
  • 2.2 Perform routine maintenance on welding equipment
  • 2.3 Set up welding equipment
  • 2.4 Select consumables in accordance with WPS

3. Weld joints using MMAW to procedure specifications

  • 3.1 Weld materials in accordance with WPS
  • 3.2 Apply post-welding heat treatment where specified
  • 3.3 Inspect welded joints visually for conformance to specifications
  • 3.4 Rectify discontinuities to ensure compliance to code requirements
  • 3.5 Maintain 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 job specifications and weld parameters from welding procedure specifications (WPS), drawings, sketches and verbal or written job instructions for performing welds using manual metal arc welding (MMAW) to code standards on at least two occasions

clean and prepare materials for welding to specifications

set up welding equipment, including performing 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 Mechanical Engineers (ASME) IX or equivalent on at least two occasions.

rectify identified weld discontinuities on at least two occasions

complete and maintain weld records related to MMAW 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 MMAW

methods for preparing plate for code standard MMAW welding

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

causes and control of distortion

requirements for maintaining weld records to code standard.

Assessment Conditions

Assessors must:

have vocational competency in performing welds to code standards using MMAW 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.
