Question 33

The welding procedure specification (choose all that apply):

Possible choices:

provides direction for welder.

depicts joint design.

depicts code requirements.

keeps a record of test results.

None of the choices.

ANSWER:

The welding procedure specification WPS is intended to provide direction for welder and depict the joint design and welding materials, parameters, and technique and code requirements. The procedure qualification record PQR is a record of test results for welds made in accordance with WPS.

requires nondestructive testing for procedure qualification and so does ASME Section IX.

requires nondestructive testing for procedure qualification but ASME Section IX does not.

does not require nondestructive testing for procedure qualification:

prohibits nondestructive testing for procedure qualification:

AWS D1.1 requires nondestructive testing for procedure qualification but ASME Section IX does not.


72

Question 36

WQTR is the acceptable alternative to PQR.

Possible choices:

True

False

ANSWER:

False. Welder qualification test record WQTR have test results for proving that a welder is qualified to weld to a certain WPS. Tests may include guided bends, breaking of fillet welds, and macroetching...etc.


73

The AWS D1.1 code qualification is for carbon and low-alloy metals with a minimum thickness of how many inches?

Possible choices:

1/2

1/3

1/4

1/6

1/8

1/12


ANSWER:

The AWS D1.1 code qualification is for carbon and low-alloy metals with a minimum thickness of 1/8 in and a maximum yield of 100 KSI.


74

Question 38

Section 3 of the AWS D1.1 prequalification lists materials from 30 KSI to _____ KSI as Group I.

Possible choices:

68

56

46

42

33


ANSWER:

The AWS D1.1 code qualification is for carbon and low-alloy metals. The prequalification Section 3 lists materials for prequalifying WPS. Group I lists lowest-yield-strength materials from 30 KSI to 46 KSI.


75

Question 39

AWS D1.3 does not cover cold formed members regardless of thickness.

Possible choices:

True

False

ANSWER:

False. AWS D1.3 Structural Steel Welding Code is the Structural Welding Code for Sheet Steel. It covers the arc welding of structural steel sheet/strip steels, which includes cold formed members equal to or less than 3/16 inch in nominal thickness.


76

Question 40

On drawings, what symbol primarily indicates the desired type of weld?

Possible choices:

weld symbols

field symbols

control symbols

supplementary symbols


ANSWER:

A weld symbol typically indicates the desired type of weld while a welding symbol is a method that represents the weld symbol on drawings.


77

Question 41

A welding symbol may consist of which of the following elements (choose all that apply):

Possible choices:

reference line

arrow

basic weld symbols

dimensions

supplementary symbols

tail

welder qualification

ANSWER:

A welding symbol may consists of these elements: reference line, arrow, basic weld symbols, dimensions, supplementary symbols, finish symbols, tail, and specification, process...etc. NOT welder qualification.


78

Question 42

With a protective welding helmet, the filter glass should be marked to show (choose all that apply):

Possible choices:

manufacturer

shade number

letter “H’

letter “T”

welding standard


ANSWER:

With a protective welding helmet, a cover plate should be placed outside the filter glass and the filter glass must be marked to show the manufacturer, the shade number, and the letter “H’ meaning it has been treated for impact resistance.


79

Question 43

A proper welding helmet would be in what color?

Possible choices:

red

yellow

dark blue

dull black

color does not matter


ANSWER:

A welding helmet is generally made of pressed fiber insulating material. In order to minimize reflection and glare, the color is usually dull black.


80

Question 44

Woolen clothing is generally more preferable than cotton:

Possible choices:

as wool is not easily burned by weld spatter.

as wool can maintain body temperature more sufficiently

as wool does not conduct electricity

as wool is totally gap-less


ANSWER:

Welders should wear work clothes without openings or gaps. Woolen clothing is preferable over cotton as wool is not easily burned by weld spatter.


81

Question 45

For Fillet welding symbols, there is an arrow that connects the welding symbol reference line to one side of the joint. This side:

Possible choices:

has no local significance at all.

always represents the arrow side of the joint.

always represents the other side of the joint.

ANSWER:

For Fillet, Groove, Flange, Flash, and Upset welding symbols, there is an arrow that connects the welding symbol reference line to one side of the joint. This side always represents the arrow side of the joint.


82

Question 46

The ______ of a welding symbol is often used to designate the welding and cutting processes.

Possible choices:

arrow head

tail

leader line

reference line

joint


ANSWER:

The tail of a welding symbol is often used to designate the welding and cutting processes as well as other information, including the welding specifications and procedures, or other supplementary information.


83

Question 47

A carburizing flame will result in chemical change in steel but not iron.

Possible choices:

True

False

ANSWER:

False. A neutral flame in most cases will have no chemical effect on the metal being welded while a carburizing flame will produce iron carbide and result in chemical change in steel and iron.


84

Question 48

When the weld symbol is placed __________ the reference line, it means the weld must be performed on the arrow side of the joint.

Possible choices:

above

below

ANSWER:

When the weld symbol is placed below the reference line, it means the weld must be performed on the arrow side of the joint.


85

Question 49

Most of the time the weld diameter is located to the ________ of the weld symbol.

Possible choices:

left

right

top

bottom

ANSWER:

Most of the time the weld diameter is located to the left of the weld symbol while the length is located to the right.


86

Question 50

A flagpole at the intersection of the reference line and the leader line means:

Possible choices:

the work should be done on site

the work should be done in the shop

the work may be done without supervision

the work should be done under supervision


ANSWER:

A flagpole at the intersection of the reference line and the leader line indicates a field weld, meaning the work should be done on site not in the shop.


87

Question 51

Local ventilation should be capable of producing a rate of air flow that is sufficient to maintain a velocity away from the welder of at least how many ft per minute?

Possible choices:

50

80

100

120

180


ANSWER:

Local ventilation should be capable of producing a rate of air flow that is sufficient to maintain a velocity away from the welder of at least 100 ft (30 m) per minute.
