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 routine manual metal arc welding (MMAW)
cleaning and preparing materials to specifications
setting up welding equipment, selecting appropriate electrodes and adjusting settings to suit application
welding materials to comply with specifications
cleaning welds for slag and splatter in accordance with SOPs.
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)
material and equipment preparation
equipment set-up and settings
appropriate welding consumables consistent with standard operating procedures
MMAW processes and properties.
Assessment Conditions
Assessors must:
have vocational competency in performing routine manual metal arc welding 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
Where possible assessment must occur in operational workplace situations. Where this is not possible or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment that reflects realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, 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.
