What is "Stick" welding?
What is considered manual welding?
What is "MIG" or MAG" or Solid Wire welding?
It is a semi-automatic process with four modes of transfer.
What are the 4 modes of transfer in GMAW?
Short-circuit (GMAW-S), Spray, Pulsed Spray (GMAW-P), Globular
What has both gas shield, and self shield?
FCAW, (FCAW-G Dual shield) (FCAW-S Innershield)
What is TIG or Heliarc?
What has a nonconsumable tungsten electrode?
What is also known as sub-arc? Shielded by granular flux.
A part of the electrical circuit.
Metallic wire used to fill the gap between the base metals to be joined. It need not be a part of the electrical circuit.
A colloquial name of electrodes/filler metal, used in SMAW process.
A continuously fed tubular electrode. Which method?
Welds are either _____ or _____, not good or bad.
acceptable or rejectable
An interruption in the typical structure of a weldment.
A discontinuity that fails to meet the minimum acceptance level stated in a code or specification.
The melting together of filler metal and base metal, or of base metal only, which results in coalescence.
Fusion which is less than complete.
the minimum depth a groove or flange weld extended from its face into a joint exclusive of reinforcement.
penetration which is less than specified.
weld metal in excess of the quantity required to fill a joint.
solid material trapped in the weld metal or between weld metal and base metl
A void or cavity formed by gas entrapment during weld solidification
fracture type discontinuity with a sharp tip and high length-to-width ratio
The protrusion of weld metal beyond the toe, face, or root of a weld, without fusion.
A groove melted into the base metal adjacent to the toe or root of a weld and left unfilled by weld metal
a depression on the face or root surface of a weld extending below the surface of adjacent base metal
metal particles expelled during welding, which do not form a part of the weld
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.
