Question 11

_______ is a filler patch that is flush to the skin when applied it is supported by and riveted to a reinforcement plate which is, in turn, riveted to the inside of the skin

Answer 11

FLUSH PATCH

Question 12

_____ is a nondestructive test for defects open to the surface in parts made of any nonporous material.

Answer 12

Penetrant inspection

Question 13

_______ are composed of free electrons under the influence of an induced electromagnetic field which are made to “drift” through metal.

Answer 13

Eddy currents

Question 14

In this method of inspection, the part under examination and the search unit are totally immersed in a liquid couplant, which may be water or any other suitable fluid

Answer 14

immersion testing

Question 15

, which is readily adapted to field use and is the method discussed in this chapter. In this method, the part under examination and the search unit are coupled with a viscous material, liquid or a paste, which wets both the face of the search unit and the material under examination.

Answer 15

contact testing

Question 16

An ________ instrument requires access to only one surface of the material to be inspected and can be used with either straight line or angle beam testing techniques

Answer 16

ultrasonic test

Question 17

Flaws are detected by measuring the amplitude of signals reflected and the time required for these signals to travel between specific surfaces and the discontinuity.

Answer 17

PULSE ECHO

Question 18

This system differs from the pulse method in that the frequency of transmission may be continuously varied. The ______ is used principally for thickness measurements when the two sides of the material being tested are smooth and parallel and the backside is inaccessible

Answer 18

resonance method

Question 19

_______ is a method of detecting invisible cracks and other defects in ferromagnetic materials such as iron and steel. It is not applicable to non magnetic materials

Answer 19

Magnetic particle inspection

Question 20

The permanent magnetism remaining after inspection must be removed by a _______ operation if the part is to be returned to service.

Answer 20

demagnetization

Question 21

This unit provides direct current for wet continuous or residual magnetization procedures. Circular or longitudinal magnetization may be used and it may be powered with rectified alternating current (AC), as well as direct current (DC). The contact heads provide the electrical terminals for circular magnetization.

Answer 21

fixed general purpose unit
