(Ultrasonic Testing)
Conventional or phased array.
40 hours 1400.00.
80 hours 2500.00.
AWS or ASME weld inspection.
16 hours 800.00.
Conventional UT features:
Will determine thickness,
material defects or velocity.
Subsurface and surface
conditions. Longitudinal,
shear or surface waves can be produced.
Conventional UT curriculum:
Theory of piezoelectric crystals,transducer construction,
acoustic impedence, velocity,
temperature effects, Snells law,
critical angles, frequency,
wavelength,wave propagation and behavior,near and far field effects, beam divergence, convergence, attenuation,
transmission and reflection coefficients, the decibel, flaw
sizing and characterization techniques. A, B and C scans,
DAC, CRT, pulser, receiver,
clock, alarm, gate, gain, delay,
range and linearity.
Phased array UT advantages:
Faster than conventional UT, flexible,mechanically reliable,
increase in misorientated defect
detectability, programmable
for complex geometries.
Phased array UT curriculum:
Principles, multiplexing crystals, probes, (VPA) virtual probe
aperture,control of focal depth,
steering angle and beam width,
wavefront, amplitude,focal laws, S scan,hardware,
software and data processing.
Note: Students are encouraged to bring their own instrument.
(Magnetic Particle Testing)
16 hour class 800.00.
Wet fluorescent or dry magnetic particle testing locates surface
and near surface defects, is used primarily to locate surface
cracks in magnetic metals.
Class curriculum covers: Principles of magnetism,
flux leakage fields,
indications, particle types,
current types, field
directions, curie point,
UV "blacklights" and defects.
(Liquid Penetrant Testing)
8 hour class 500.00.
Type 1 fluorescent or type 2 visible dye penetrant testing gives information about surface conditions and is used to
locate surface cracks and
defects in ferromagnetic and nonmagnetic aluminum,
some stainless steel,
titanium and some
nonmetals.
Class curriculum covers: Principles, types and methods, developers, process limitations,
UV "blacklights" and defects.
(Certified Weld Inspector)
16 hour class 800.00
The class covers:
The basics required to
prepare the student for the American Welding Society exam, including weld processes, codes, NDT methods,
weld symbols, destructive tests,weld types,
discontinuity types,
weld inspection gauges,
heat control,metallurgy,
records and overall
job requirements.
Remote visual inspection (RVI) digital imaging
and data processing is also discussed.
Note:
The above classroom
training hours and
information are minimums
required for qualification by most industries, codes and
employers and are the
minimums covered in class.
