Ultrasonic Testing Level-1 Training
Course (5 days/40 hours)
Course Description:
Course is useful for
Inspectors and NDE Personnel Training for Manufacturers,
Maintenance & Service Companies. UT
is one of the most widely used volumetric
testing method.
Course covers theoretical aspects,
demonstrations & practical hand-on lab sessions
using Contact and Immersion Testing Equipment. UT
Level-1 is designed to covers the topics as per ISO9712:
2000; CGSB48.9712; SNT-TC-1A.
UT Level-I : CGSB defines Level-1 as qualified to
properly perform Specific Calibration, Specific Ultrasonic
Test under the supervision & instructions from
Level-2/3, determine Specific Evaluation for Acceptance
or Rejection according to written Instructions &
to Record Results.
