Application

This unit of competency defines the skills and knowledge required to perform flux core arc welding (FCAW) on heavy or light metal fabrications.
Weld quality would conform to AS 1554 General Purpose and American Bureau of Shipping (ABS) or equivalent.
Where the interpretation of technical drawings is required unitMEM09002Interpret technical drawing should also be selected.
Where thermal processes, hand and/or power tools are required the appropriate specialisation units 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 sketches and verbal or written job instructions for welding using flux core arc welding process (FCAW) to the specified standard
• selecting appropriate weld and joint preparation methods
• consistently weld materials to the specified standard or equivalent using semi-automatic machines and consumables while preventing distortion
• rectifying any defects
• completing weld records related to FCAW 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)
• types of gases and their uses
• relationships between amperage/wire feed, voltage, gas flow, electrode, contact tip and material
• material preparation
• polarity
• electrode stickout
• joint preparations
• electrode classification
• causes of distortion for materials when welded
• causes of weld defects and methods of rectification
• standards for FCAW, including AS 1554 General Purpose and any other equivalent standards.

Assessment Conditions

• Assessors must:
• have vocational competency in welding using flux core arc welding 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
• 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.
