Level 1

Alternating Current Field Measurement

Name Of Tutor

A highly practical course with relevant theoretical background enabling students to achieve a basic understanding of ultrasonic inspection. On completion of the course candidates will be able to calibrate a flaw detector with both compression and shear wave probes, record accurate thickness measurements and locate and size lamination in steel plate. In addition, students will be able to select the correct compression/shear wave probes for the examination of welded butt joints, locate and size defects and finally produce acceptable reports

Alternating current field measurement (ACFM) is an electromagnetic inspection technique for the detection and sizing of surface breaking cracks in metallic components and welds. This NDT technique combines the advantages of the alternating current potential drop (ACPD) technique and Eddy Current Testing (ECT).

Special Note

It has been agreed by PDTC (ICorr) to add an experience assessment to all ICorr certifications for personnel engaged in painting and coating inspection. Full details of the changes can be provided on request.
