A) 80
B) 85
C) 90
D) 95

Answer 1

C

Question 2

The type of metal-such as steel, aluminum, stainless steel, and titanium-being welded will require a change in the certification.

Answer 2

True

Question 3

____ looks to see that the weld is uniform in width and reinforcement.

A) Bend test
B) Visual inspection
C) AWS entry-level certification
D) Knowledge test

Answer 3

B

Question 4

The Acceptance Criteria for Bend Test requires that n o single indication shall exceed ____ in. measured in any direction on the surface.

A) 1/8
B) 2/8
C) 3/8
D) 4/8

Question 5

Starting and stopping weld beads in corners should be avoided because this often results in defects.

Question 6

____ is the application of heat to the metal after welding. It is used to slow the cooling rate and reduce hardening.

A) Annealing
B) Normalizing
C) Preheating
D) Postheating

Question 7

All welding jobs require that the welder be certified.

Question 8

The weld specimen must first pass visual inspection before it can be prepared for bend testing.

Question 9

A written test must be passed with a minimum grade of ____% on all areas except safety.

A) 60
B) 65
C) 70
D) 75

Question 10

Welder certification can be divided into ____ major areas.

A) two
B) three
C) four
D) five

Question 11

For all welds, the welding bead will need to be restarted after a welder stops to change electrodes.

Question 12

The Visual Inspection Criteria for Entry-Level Welders requires that the undercut shall not exceed the lesser of ____% of the base metal thickness or 1/32 in. (0.8 mm).

A) 10
B) 12
C) 14
D) 15

Question 13

When a weld bead is nearing completion, it should be tapered so that when it is restarted the buildup will be more uniform.

Question 14

The Visual Inspection Criteria for Entry-Level Welders requires that the frequency of porosity shall not exceed one in each 4 in. (100 mm) of weld length, and the maximum diameter shall not exceed ____ in.

A) 1/32
B) 2/32
C) 3/32
D) 4/32

Question 15

Being certified does not mean that a welder can weld everything, nor does it mean that every weld that is made is acceptable.

Question 16

Being qualified or certified in one area of welding ensures that a welder can make quality welds in other areas.

Question 17

Changes in weld type such as groove or fillet welds do not require a new certification.

Question 18

A test taken in the ____ position would usually allow the welder to work in the flat, horizontal, and vertical positions, depending on the code requirements.

A) horizontal
B) vertical
C) longitudinal
D) flat

Question 19

All welding processes can be tested for qualification and certification.

Question 20

The Acceptance Criteria for Bend Test requires that the sum of the greatest dimensions of all indications on the surface which exceed 1/32 in. (0.8 mm) but are less than or equal to 1/8 in. (3.2 mm) shall not exceed _____ in.

A) 1/8
B) 2/8
C) 3/8
D) 4/8

Question 21

In a transverse ____________________ bend, the weld is perpendicular to the longitudinal axis of the specimen and is bent so that the weld face becomes the tension surface of the specimen.

Question 22

The ____________________ interpass temperature is usually the same as the preheat temperature. If the plate cools below this temperature during welding, it should be reheated.

Question 23

A(n) ____________________ interpass temperature occurs when the weld bead cannot be controlled because of a slow cooling rate.

Question 24

In a transverse ____________________ bend, the weld is perpendicular to the longitudinal axis of the specimen and is bent so that the weld root becomes the tension surface of the specimen.

Question 25

Welders who have passed a qualification or certification test are referred to as qualified welders; if proper written records are kept of the test results, they are referred to as ____________________.
