ASNT BASIC Level 3 Method NDT

Alloy subjected to cyclic tensile will most likely exhibit which type of defect. Corrosion. Crack. Lap. Seam.

Common gas tracer used because it is inert, nontoxic, a small molecule, nonflammable, and inexpensive is. Hydrogen. Oxygen. Nitrogen. Helium.

What test would be used on liquid penetrant DIP tanks, containing new hydrophilic emulsifier to assure proper concentration. Flash point. Wettability. Fluorescence. Measurement refracted.

Surface roughness measured as the arithmetical average deviation of heigh and depth from mid-point called the. Average waviness value. Root means square value. Real surface deviation. Lower Lay limit.

A nonferrous metal provides combined properties that make it a structural metal suitable for many applications considering cost and weight is. Copper. Magnesium. Aluminum. Nickel.

One way to calibrate an ultrasonic testing system to adjust the sensitivity of response from series of flat bottom holes of differing depth to 50 percent of screen height in order to obtain ?. resolution level. reference line. refraction angle. Exit Point.

Rough surface can cause undesirable effects when performing an ultrasonic testing. One of this effect is. a change in the material sound velocity. the need for less viscous couplant. focusing of the sound beam. an increase on the width of surface echo and consequent loss of resolving power.

The thread on pipe end should normally be check visually using. Cambridge gauge. Hi low gauge. Pith depth gauge. Profile gauge.

Eddy Current technique typically especially need excitation frequency in the range of ?. 6 -10Hz. 20-50Hz. 100Hz – 10Mhz. 100MHz +.

Ideally sampling plan should. assumes 85% confidence level on 90% of the part. represents the smallest sample possible. be selected on a non-random basis 50% of the production item. accepts all good lots and reject all bad lots of a part.

Nickel when performing visual testing if illumination of the inspection surface inadequate the technician should. delays the usual test for one week. moves the test piece to an inspection area with more light. use magnifying lens. performs magnetic particle test.

Water contamination of lipophilic can be tolerated approximately. 5%. 10%. 15%. 20%.
