Magnetic Particle Testing Level
1 & 2 Training Course (40 hour)
Course Description:
MT course
is useful for NDE , QC Inspectors and Personnel Training
for Manufacturers, Maintenance & Service Companies.
MT is used to locate surface and sub-surface discontinuities
in ferrous material, by inducing intense Magnetic field.
Course covers theoretical aspects,
demonstrations & practical hand-on lab sessions
using both portable and stationary equipment for different
MT techniques. MT is designed to covers the topics
as per ISO9712; CAN/CGSB48.9712; SNT-TC-1A.
MT Level-2: CGSB defines Level-2 as qualified to
perform Magnetic Particle Testing as per the relevant
MT procedure and interpret and evaluate test results
with respect to applicable Code, Standard and Specifications.
MT 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.
