Ultrasonic Testing Level-2 Training
Course (10 days/80 hours)
Course Description
Course is useful for
Inspectors and NDE Personnel Training for Manufacturers,
Maintenance & Service Companies. Course covers Theoretical aspects
& Practical Hand-on lab sessions using Contact
and Immersion Testing Equipment. UT Level-2 is designed
to covers the topics as per ISO9712: 2000; CGSB48.9712;
SNT-TC-1A.
UT Level-2: CGSB defines Level-2 as qualified to
perform Ultrasonic Testing as per the relevant UT
procedure and interpret and evaluate test results
with respect to applicable Code, Standard and Specifications.
UT L-2 is qualified to Set-up & Calibrate the
Equipment, Organize and Report the Results. Level-2
could also impart On-job Training & Guidance to
Trainee and Level-I Personnel.
