Liquid Penetrant Testing (PT)
Level-1 & 2 Training Course (5 days/40 hours)
Course Description:
PT Course is useful for Inspectors & NDE Personnel Training
for Manufacturers, Maintenance and Service Companies.
Liquid Penetrant Testing (PT) is a quick and reliable
NDE method, usually used to detect discontinuities like crack or porosity that are open to the surface. PT Course covers theoretical aspects, demonstrations
& practical hand-on lab sessions using both portable
and stationary equipment for different PT techniques.
Course is designed to covers the topics as per ISO-9712,
CAN/CGSB48.9712 & SNT-TC-1A.
PT Level-2: CGSB defines Level-2 as qualified to Calibrate the Equipment, perform Liquid Penetrant as per the relevant procedure and interpret , evaluate and Report the Results test results with respect to applicable Code, Standard and Specifications. Level-2 could also impart
On-job Training & Guidance to Trainee and Level-I Personnel.
