• apply planning and organising skills to own work activities, including making good use of time and resources, sorting out priorities and monitoring one's own performance
• interact effectively with other persons both on a one-to-one basis and in groups, including understanding and responding to the needs of a customer and working effectively as a member of a team to achieve a shared goal
• establish safe and effective work processes which anticipate and/or resolve problems and downtime, to systematically develop solutions to avoid or minimise reworking and wastage
• use mathematical ideas and techniques to calculate time, assess tolerances, apply accurate measurements, calculate material requirements and establish quality checks
• use workplace technology related to welding systems, including the use of measuring equipment and communication devices and the reporting/documenting of results

Required knowledge 

A working knowledge of:

• WHS regulations/requirements, equipment, material and personal safety requirements
• types of metals
• types of fluxes, rods and their application
• TIG welding processes and techniques
• equipment maintenance procedures
• workplace guidelines regarding acceptable tolerance levels to be considered as per job sheet and manufacturer/component supplier specifications
• procedures for reporting faults and material defects
• work organisation and planning processes
• enterprise quality processes

EVIDENCE GUIDE 

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

It is essential that competence is fully observed and there is ability to transfer competence to changing circumstances and to respond to unusual situations in the critical aspects of:

• observing safety procedures and requirements
• communicating effectively with others involved in or affected by the work
• selecting methods and techniques appropriate to the circumstances
• completing preparatory activity in a systematic manner
• setting up, operating and maintaining TIG welding, safety, lifting and measuring equipment
• completing a range of gas tungsten arc (TIG) welding tasks to specifications.

Context of , and specific resources for assessment 

• Application of competence is to be assessed in the workplace or simulated worksite.
• Assessment is to occur using standard and authorised work practices, safety requirements and environmental constraints.
• Assessment is to comply with regulatory requirements, including Australian standards.
• The following resources should be made available:

• workplace location or simulated workplace
• materials relevant to gas tungsten arc (TIG) welding
• equipment, hand and power tooling appropriate to gas tungsten arc (TIG) welding
• activities covering mandatory task requirements
• specifications and work instructions.

Method of assessment 

• Assessment must satisfy the endorsed Assessment Guidelines of AUR12 Automotive Industry Retail, Service and Repair Training Package.
• Assessment methods must confirm consistency and accuracy of performance together with application of underpinning knowledge.
• Assessment must be by direct observation of tasks, with questioning on underpinning knowledge and it must also reinforce the integration of key competencies.
• Assessment may be applied under project-related conditions and require evidence of process.
• Assessment must confirm a reasonable inference that competence is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.
• It is preferable that assessment reflects a process rather than an event and occurs over a period of time to cover varying quality circumstances. Evidence of performance may be provided by customers, team leaders/members or other persons subject to agreed authentication arrangements.
• Competence in this unit may be assessed in conjunction with other functional units which together form part of the holistic work role.
