CWB BOOK 4 Welding Processes &
Equipment Exam Questions and
Answers Verified Solutions Latest
Update (2026/2027)
Question:
AWS groups welding processes based primarily on?
Answer:
Mode of energy transfer,
and the influence of capillary action in the effecting distribution of filler
metals in the joint
Question:
AWS defines welding as?
Answer:
A joining process producing coalescence of materials
by heating them the the welding temperature with, or without the
application of pressure or by
the application of pressure alone, and without or without the use of filler
metal.
Question:
AWS welding processes are grouped into which major following categories.
,Answer:
ARC welding (AW), Solid state welding (SSW), Resistence welding(RW),
Oxyfuel gas
welding(OFW), Soldering(S), Brazing(B), other welding welding, Allied
processes (such as cutting
and thermal spray.)
Question:
What are the 2 main methods of ARC shielding welding?
Answer:
Flux shielding, Gas
shielding
Question:
Which elements don't conduct any electricity at room temp?
Answer:
Oxygen, Nitrogen
and Carbon Dioxide
Question:
How is a welding ARC formed?
Answer:
High Current is forced to flow across a gap
between 2 electrodes at relatively low voltage
,Question:
Does ARC welding require application of pressure to cause fusion?
Answer:
No
Question:
What would be 2 examples of Autogenous weld?
Answer:
Gas Tungsten ARC & Electron
Beam welding
Question:
Is filler metal used in Autogenous weld?
Answer:
No
Question:
All the electrical energy supplied by the power source is convered into?
Answer:
Heat
(current * voltage)
, Question:
ARC efficiency for some of the commonly used ARC welding processes is?
Answer:
Submerged arc welding (90-95%)
Shielded metal arc, gas metal and flux cored arc welding (65%-85%)
Gas tungsten arc welding (20-45%)
Question:
Higher arc efficiency usually means for a given arc energy?
Answer:
A greater amount
of weld metal is deposited and the work piece cools at a comparatively
slowly rate.
Question:
What are the 4 steps in any welding setup of the continuous drop in voltage
from the lower
most point of contact to the work piece?
Answer:
There is a drop in voltage over the
electrode extension,
the volt drop over the arc length,
Next to the cathode spots are small thin gaseous regions called the anode
drop zone and
cathode drop zone,
Between the 2 drop zones there is a arc column with a relatively small drop
