Which organization has the most commonly used welding codes? - ✔✔AWS, API, and ASME
Visual inspection detects flaws just below the surface of magnetic parts. - ✔✔False
Penetrate testing is the most frequently used NBT method. - ✔✔False
Acid is applied to a test specimen in the Etch testing method. - ✔✔True
Nondestructive and destructive testing verify the integrity of the weld and the ability of the
welder. - ✔✔True
The Rockwell tester uses a diamond cone or a steel ball which is pressed into the base metal. -
✔✔True
One advantage of the Eddy current testing system is _______. - ✔✔The ability to detect very
small cracks in or near the surface of the material.
_____ testing the hardness of the material by a measurement of the indentation caused by a
metal ball applied at a constant pressure for a controlled period of time. - ✔✔Vernell
With hardness testing variations can be electrical, conductivity, or magnetic permeability of the
test object or the presents of any flaws will cause a change in the Eddy current in corresponding
change in the phase in the amplitude of the measured current. - ✔✔False
_______ is a gel that helps the transducer make contact with the part and make a better
transmission of sound waves into the particle being tested. - ✔✔Couplet
