A) industrial
B) structural
C) robotic
D) ship

Answer 3

B

Question 4

All root passes are ground.

Question 5

One way of cleaning up trapped slag or other similar root weld face problems is to use a hot pass.

Question 6

The ____ is commonly used in fabrication shops where structures or small systems can be positioned for the convenience of the welder.

A) horizontal rolled pipe position
B) vertical reversed pipe position
C) horizontal fixed pipe position
D) vertical fixed pipe position

Question 7

Root suck back is caused by the surface tension of the molten metal trying to pull itself into a ball, forming a(n) ____.

A) complete root surface
B) V-groove
C) concave root surface
D) incomplete root surface

Question 8

In the 2G ____ , the pipe is vertical and the weld is horizontal.

A) horizontal rolled pipe position
B) vertical reversed pipe position
C) horizontal fixed pipe position
D) vertical fixed pipe position

Question 9

Rolling horizontal pipe is the easiest and fastest way of making horizontal pipe welds.

Question 10

Any time an E7018 low-hydrogen-type electrode is to be used, the weave pattern, if used, must not be any larger than ____ the diameter of the electrode.

A) one-and-a-half times
B) two times
C) two-and-a-half times
D) three times

Question 11

Pipe welding is used to both fabricate piping systems and to build structural items.

Question 12

Fitting pipe together and holding it in place for welding become more difficult as the diameter of the pipe gets larger.

Question 13

The root face helps a welder control penetration, not root suck back.

Question 14

Grooved pipe welds are made up of several separate weld joints.

Question 15

Although pipe and tubing may look alike, they have different types of specifications and uses.

B) vertical reversed pipe position
C) horizontal fixed pipe position
D) vertical fixed pipe position

Question 19

Question 20

The ____ is used to quickly burn out small amounts of slag trapped along the edge of the root pass.

A) filler pass
B) hot pass
C) root pass
D) cover pass

Question 21

The final covering on a grooved weld is referred to as the cover pass or ____________________.

Question 22

Tubing sizes are always given as the outside ____________________.

Question 23

The filler pass(es) may be either a series of stringer beads, or a(n) ____________________.

Question 24
