Answer : B

Question 2

When welding using the shielded metal arc welding (SMAW) process, which of the following best describes the appearance of excessive penetration on a radiograph?

AA lighter density in the center of the width of the weld image, either extended along the weld or in isolated circular drops.

BAn irregular darker density near the center of the width of the weld image along the edge of the root pass image.

CAn abrupt density change across the width of the weld image with a straight longitudinal darker density line at the center of the width of the weld image along the edge of the density change.

DA localized darker density with fuzzy edges in the center of the width of the weld image.

Answer : B

Question 3

For what maximum outside diameter may a radiographic technique be used in which the radiation passes through two walls and the weld in both walls is viewed for acceptance?

A1.5 in. (38.0 mm)

B2.5 in. (63.5 mm)

C3 in. (76.2 mm)

D3.5 in. (90.0 mm)

Answer : C

Question 4

As a result of welding, metals with a high coefficient of thermal expansion are:

AMore susceptible to distortion during welding.

BLess susceptible to cracking during welding.

CMore susceptible to brittle fracture.

DLess susceptible to brittle fracture.

Answer : A

DThere is minimal postweld cleanup.

Answer : B

Question 7
