- This is an 80 hour (2 week) course, based on a portable phased array unit, which requires understanding on how to set up and interpret phased arrays.
- The course will cover: principles of phased arrays, the OmniScan instrument, scanning, calibration, software, data analysis principles, and views.
- Specialized inspections will be addressed, e.g. turbines, tubes, pipelines, bars and complex geometries.
- Examination will be by multiple choice questions on the three areas of Castings, Wrought Products and Welds. Assembly of equipment, testing, interpretation of data and development of a suitable phased array procedure is also required.
The certification exam at the end of the course comprise of the following:
- Multiple choice theory exam
- Data collection exam: This requires assembly and calibration of the equipment with appropriate arrays, wedges and encoders followed by collection of data from a weld and a cast or wrought product. The data shall be saved in a format to be analyzed.
- Data analysis: Analysis of electronic data sets from weldments, castings and wrought products. The data shall be analyzed using offline computer software such as 'Tomoview'.
