Summary:

This 40 hour course is designed to provide entry-level instruction to technicians who want to learn how to do Phased Array UT inspections. Some of the basic fundamentals such as beam forming and focusing are discussed, along with equipment and technique limitations. This course is to help the technician properly calibrate before the scan; understand how to set up a proper scan according to a Scan Plan or Written Instruction; use Manual Phased Array UT to scan a weld for defects; collect and save data for future analysis; set up and scan a weld using a semi-automatic or manual scanner; and set up and scan a pipe for internal corrosion assessment.

Very little of this course is spent on data interpretation. As an entry-level course, the emphasis is on understanding the Scan Plan or Written Instruction, becoming familiar with the PAUT unit’s menus, setting up a scanner, and making sure the scan is completed properly. Discussions about trouble-shooting various scanners will be encouraged.

Minimum Requirements:

The candidate needs to have a strong understanding of conventional UT. This requires candidates to have successfully completed a CGSB Level 2 course, or equivalent.

    4. Where is the data saved?
    5. Is the correct data collected?
    6. Settings for efficient file sizes.
  • Data retrieval
    1. From the PAUT Flaw detector
    2. From other devices with proper software
  • Following a Scan Plan or Written Instruction
    1. ES Beamtool Scan Plan development
    2. Manual Scan Plan development
    3. Using a Written Instruction
    4. Choosing proper start element, # of elements, etc.
    5. Setting up multiple groups
  • Checklist before scanning
    1. Element Check
    2. Calibrations
    3. File Name
    4. Saved File Location
    5. Scanning Sensitivity
    6. Gate Settings
    7. Scan start and end
    8. Data Evaluation – make certain the data collected is correct and complete
  • Practical exercises:
    1. Calibration of manual scanning probe and wedge
    2. Calibration of mechanical scanning probe and wedge
    3. Encoder calibration
    4. File naming, saving, and retrieval
    5. Set up scan according to Scan Plan
    6. Scan full weld using multiple groups (if available).

Certification will be given to candidates who successfully complete the course, with an aggregate score of at least 80%, with no marks below 70% in any section.

Homework assignments may be completed at the end of the day, using equipment provided.

The written final exam will consist of 80 written multiple choice questions. At some time during the course, the candidate is required to set up and record a weld scan with 2 groups. Calibrations will be recorded and graded.
