SMAW

2

What is considered manual welding?

SMAW

3

What is "MIG" or MAG" or Solid Wire welding?

GMAW

4

It is a semi-automatic process with four modes of transfer.

GMAW

5

What are the 4 modes of transfer in GMAW?

Short-circuit (GMAW-S), Spray, Pulsed Spray (GMAW-P), Globular

6

What has both gas shield, and self shield?

FCAW, (FCAW-G Dual shield) (FCAW-S Innershield)

7

What is TIG or Heliarc?

GTAW

8

What has a nonconsumable tungsten electrode?

GTAW

9

What is also known as sub-arc? Shielded by granular flux.

SAW

10

A part of the electrical circuit.

Electrode

11

Metallic wire used to fill the gap between the base metals to be joined. It need not be a part of the electrical circuit.

Filler Metal

12

A colloquial name of electrodes/filler metal, used in SMAW process.

Welding Rod

13

A continuously fed tubular electrode. Which method?

FCAW

14

Welds are either _____ or _____, not good or bad.

acceptable or rejectable

15

An interruption in the typical structure of a weldment.

Discontinuity

16

A discontinuity that fails to meet the minimum acceptance level stated in a code or specification.

defect

17

The melting together of filler metal and base metal, or of base metal only, which results in coalescence.

Fusion

18

Fusion which is less than complete.

Incomplete fusion

19

the minimum depth a groove or flange weld extended from its face into a joint exclusive of reinforcement.

penetration

20

penetration which is less than specified.

incomplete penetration

21

weld metal in excess of the quantity required to fill a joint.

reinforcement

22

solid material trapped in the weld metal or between weld metal and base metl

inclusions

23

A void or cavity formed by gas entrapment during weld solidification

porosity

24

fracture type discontinuity with a sharp tip and high length-to-width ratio

cracks

25

The protrusion of weld metal beyond the toe, face, or root of a weld, without fusion.

overlap

26

A groove melted into the base metal adjacent to the toe or root of a weld and left unfilled by weld metal

undercut

27

a depression on the face or root surface of a weld extending below the surface of adjacent base metal

underfill

28

metal particles expelled during welding, which do not form a part of the weld

spatter

29

a discontinuity consisting of any localized re-melted metal or change in the surface profile of any part of a weld or base metal resulting from an arc.

arc strike

30

A document providing the required welding variables for a specific application to assure repeat-ability by properly trained welders and welding operators.

welding procedure specification (WPS)
