Critical aspects of evidence
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
Relationship to other units
Competence in this unit may be assessed in conjunction with other functional units which together form part of the holistic work role
Underpinning knowledge
A working knowledge of:
OH&S 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
Specific key competencies, underpinning and employability skills required to achieve the performance criteria
These include a number of processes that are learned throughout work and life, required in most jobs. Some of these are covered by the national key competencies, although others may be added. The details below highlight how these competencies are to be applied in the attainment of this unit.
Application of the key competencies in this unit are to satisfy the nominated level in which:
Level 1 - relates to working effectively within set conditions and processes;
Level 2 - relates to management or facilitation of conditions or processes; and
Level 3 - relates to design, development and evaluation of conditions or process.
How will the candidate apply the following key competency in this unit? The candidate will need to:
Collect, analyse and organise information
Apply research and interpretive skills sufficient to locate, interpret and apply manufacturer/component supplier procedures, workplace policies and procedures
Apply analytical skills required for the identification and analysis of technical information
(Level 1)
Communicate ideas and information
Apply plain English literacy and communication skills in relation to dealing with customers and team members
Apply questioning and active listening skills for example when obtaining information from customers
Apply oral communication skills sufficient to convey information and concepts to customers
(Level 1)

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
(Level 1)
Work with others and in a team
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
(Level 1)
Solve problems
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
(Level 1)
Use mathematical ideas and techniques
Use mathematical ideas and techniques to calculate time, assess tolerances, apply accurate measurements, calculate material requirements and establish quality checks
(Level 1)
Use technology
Use workplace technology related to welding systems, including the use of measuring equipment and communication devices and the reporting/documenting of results

Context of 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
Method of assessment
Assessment must satisfy the endorsed assessment guidelines of the automotive industry's RS&R 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
