Course Description

This unit covers performing ultrasonic thickness testing in a range of industrial applications. Knowledge of metallurgy associated with the level of application in this unit is required.

This unit applies to inspecting, interpreting and reporting on ultrasonic testing techniques of fabrications, structures and components. Testing is across a wide range of industries and includes identifying abnormalities such as thickness measurement of corrosion, laminations of nonferrous/ ferrous alloys steels, composite materials. The work can relate to scheduled and unscheduled maintenance activities using general tools and specific ultrasonic testing equipment as specified in maintenance documentation, testing procedures or operators instructions.
Actual and potential defects are to be considered, together with ongoing abnormalities in fabrications, components and structures on a wide range of applications. Ultrasonic tests are performed on critical component or structural zones, and may require re-assessment of competency at regular intervals in accordance with Australian standards and/or other relevant standards. All testing must be completed with particular attention to personal safety and OH&S
regulations. Certification against Australian standards may be achieved where assessment in this unit of competency is
carried out in conjunction with an examining authority as described in ISO 9712. Materials and chemicals which are subject to codes and regulations – for example, chemicals, explosives, solvents, dangerous materials, acids, or noxious waste products – are subject to safe work habits and must be stored and used in
accordance with safe work practices.

Overview of Assessment

Assessment may incorporate a variety of methods including written/oral activities and demonstration of practical skills to the relevant industry standards. Participants are advised that they are likely to be asked to personally demonstrate their assessment activities to their teacher/assessor. Feedback will be provided throughout the course.

Evidence of student’s competence can be gathered through a variety of ways including:
• observation of processes and procedures;
• oral and/or written questioning on required knowledge and skills;
• testimony from supervisors, colleagues, clients and/or other appropriate
• inspection of the final product or outcome;
• a portfolio of documentary evidence.

Graded Assessment out of 100 Marks will be based on the results obtained for Assignments, Practical Reports & Unit Tests.
Students must gain a pass in ALL forms of assessment in order to gain this competency.
