Ultrasonic Testing Level II Training
Start Date:
3/23/2015
End Date:
4/3/2015
Class is hosted by Aerial Energy Resources, and will be held in Belle Vernon, Pennsylvania. For more information, visit our website or email services@aertesting.com.
Course Description
The Ultrasonic Testing Level II course training is provided as required by ASNT SNT-TC-1A and CP-189 for Ultrasonic Testing Level II technicians using the UT method. This class is broken into two parts. Students will test after the first 40 hours and after the second 40 hours.
Ultrasonic inspection is a nondestructive method in which beams of high-frequency sound waves are introduced into materials for the detection of surface and subsurface flaws in the material. The sound waves travel through the material with some attendant loss of energy (attenuation) and are reflected at interfaces. The reflected beam is displayed and then analyzed to define the presence and location of flaws or discontinuities.
The degree of reflection depends largely on the physical state of the materials forming the interface and to a lesser extent on the specific physical properties of the material. For example, sound waves are almost completely reflected at metal/gas interfaces. Partial reflection occurs at metal/liquid or metal/solid interfaces, with the specific percentage of reflected energy depending mainly on the ratios of certain properties of the material on opposing sides of the interface.
Cracks, laminations, shrinkage cavities, bursts, flakes, pores, disbonds, and other discontinuities that produce reflective interfaces can be easily detected. Inclusions and other inhomogeneities can also be detected by causing partial reflection or scattering of the ultrasonic waves or by producing some other detectable effect on the ultrasonic waves.
The Ultrasonic Testing Level II training provides classroom instruction on wave propagation theory, UT applications and uses, setup and calibrations of equipment and evaluation of flaws using the Longitudinal Wave and Shear Wave modes.
