Assessment tasks will be designed to reinforce and extend knowledge and skill competence within set and controlled parameters in accordance with each unit's learning outcomes and performance criteria requirements, including the setting of work based practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines. Students will be expected to demonstrate the following required skills: - welding to conform to Australian Standard 1554 Structural Purpose, Bureau Det Norse Verticas or equivalent; - interpreting technical drawings and weld specifications relating to advanced GTAW; - using hand and power tools to prepare and weld material using GTAW; - using measurement and numeracy skills relating to advanced GTAW and preparation; - selecting equipment and consumables appropriate to task, and; - using visual identification of faults/defects. Students will also be expected to demonstrate the following knowledge: - in-depth knowledge of the properties and characteristics of a wide range of materials; - requirements to conform to Australian Standard 1554 Structural Purpose, Bureau Det Norse Verticas or equivalent; - weld procedures and requirements; - different welder identification systems such as numbering, bar coding, paint coding, letter stamps; - safe welding practices; - use and application of personal protective equipment for GTAW, and; - hazards and control measures related to GTAW.
