Application

This unit of competency defines the skills and knowledge required to carry out advanced welding using gas metal arc welding (GMAW).
Welds are associated with a range of structural sections and/or plate and/or pipe for general fabrication using ferrous and non-ferrous materials. Weld quality would typically conform to AS 1554 Structural Purpose or equivalent.
Where advanced manual thermal cutting, gouging and shaping is required unitMEM05008Perform advanced manual thermal cutting, gouging and shaping should 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 on at least two (2) occasions and include:
• following work instructions, standard operating procedures (SOPs) and safe work practices
• identifying and interpreting specifications from drawings, sketches and verbal or written job instructions for performing advanced welding using gas metal arc welding (GMAW) process to AS 1554 Structural Purpose
• selecting appropriate weld and joint preparation methods
• consistently weld materials to AS 1554 Structural Purpose or equivalent using AC or DC welding machines and electrodes while preventing distortion
• rectifying any defects
• completing and maintaining weld records related to GMAW Structural Purpose 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)
• in-depth knowledge of the properties and characteristics of a wide range of materials
• requirements to conform to AS 1554 Structural Purpose or equivalent
• weld procedures and requirements
• different welder identification systems, including numbering, bar coding, paint coding and letter stamps
• causes of weld defects and methods of rectification.

Assessment Conditions

• Assessors must:
• have vocational competency in performing advanced welding using GMAW 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.
• 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.
