CWB Level 1 Inspector - Basic Welding
Inspection
Are inspectors required to verify welding strategies?
A) Yes
B) No
C) Only if special
D) Only upon engineer request - ANS-A
Because of the variety of welded systems requiring inspection, an inspector is required to be
gifted in all varieties of inspection methods. (True/False) - ANS-TRUE
Each penetrameter has numbers affixed to it figuring out:
A) the fabric and the minimal thickness of the plate.
B) the fabric and the maximum thickness of the plate.
C) which holes must seem as photographs at the radiograph.
D) use with either X-ray or gamma ray. - ANS-B
Gamma radiation emitted by using a radioscope of Co-60 has wavelengths which might be
longer than Ir-192. (True/False) - ANS-FALSE
In an X-ray tube, the energy generated from producing the X-ray beam is:
A) 70% heat and 30% X-rays.
B) 80% warmness and 20% X-rays.
C) ninety% heat and 10% X-rays.
D) ninety nine% warmth and 1% X-rays. - ANS-D
In gamma radiography, Cobalt-60 has wavelengths a good deal shorter than Iridium-192 and
consequently:
A) has extra penetrating electricity.
B) has less penetrating strength.
C) is used on thinner materials.
D) is used on high-quality grained material. - ANS-A
Liquid penetrant examination is:
A) incapable of exposing discontinuities not open to the surface.
B) faster than magnetic particle inspection.
C) extra high-priced than ultrasonic inspection.
D) more dangerous than radiography. - ANS-A
Magnetic particle inspection makes use of a magnetic subject that is brought on in
non-magnetic substances. (True/False) - ANS-FALSE
Radiographic strategies that hire X-rays are more secure to use than Gamma-rays because:
A) fewer X-rays are used than Gamma-rays to provide the equal film density.
B) Gamma-rays are safer than X-Rays because they have a tendency to be of specific
wavelengths and consequently their penetrability is extra comfortably anticipated.
C) X-Rays are more secure because they can be grew to become off via eliminating the
source of power.
D) they may be less powerful than Gamma-rays and therefore less complicated to guard. -
