Application

This unit of competency defines the skills and knowledge required to identify material properties and select appropriate welding processes that would typically conform to AS 1554 General Purpose and American Bureau of Shipping (ABS) or equivalent, to achieve safe and effective welding outcomes.
This unit applies to all types of welding and includes the identification of properties and characteristics of all commonly used metals, and selection of appropriate welding techniques to ensure integrity of materials is maintained during welding processes.
This unit can only be selected in conjunction with one or more of the following units:
• MEM05015 Weld using manual metal arc welding process
• MEM05017 Weld using gas metal arc welding process
• MEM05019 Weld using gas tungsten arc welding process
• MEM05023 Weld using submerged arc welding process
• MEM05047 Weld using flux core arc welding process
• MEM05055 Weld using oxy fuel gas welding process
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 properties of common used metals
• identifying potential contingencies and considering solutions
• identifying and selecting appropriate welding process and the effects of the welding process on materials
• identifying processes for cleaning and preparing metals and the role of contaminants in welding flaws.

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)
• properties and characteristics of commonly used metals and materials
• basic metallurgy principles associated with alloys and grades of metals
• uses and purposes of various metals
• distortion prevention measures for various metals
• different types of electrodes
• hazards associated with the use of chemicals and the fumes emitted by welding processes.

Assessment Conditions

• Assessors must:
• have vocational competency in selecting welding processes 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.

Foundation Skills

• {'skill': 'Foundation Skills', 'description': 'This section describes those required skills (reading, writing, oral communication and numeracy) that are essential to workplace performance in this unit of competency.\nFoundation skills essential to performance are explicit in the performance criteria of this unit of competency.'}
