  • Ultrasonic Testing – UT Level 1 & 2

This course offers a high practical content and relevant theoretical background to enable students to achieve a good understanding of ultrasonic inspection.

Candidates on completion of the course will be able to calibrate a flaw detector with both compression and shear wave probes, record accurate thickness measurements and locate and size laminations in steel plate, and finally produce acceptable reports.

This course will enable the student to measure the remaining wall thickness of materials and inspect the materials by straight beam.

The course is suitable for candidates who are wishing to progress towards any of the examination qualifications. The course has a high practical content; all equipment is provided.
