CWB 2 VISUAL WELD INSPECTOR ACTUAL
EXAM 2026 QUESTIONS WITH ANSWERS
GRADED A+
◉ The weld heat affected zone is: Answer: the portion of the base metal
adjacent to the weld metal whose properties have been changed due to
the heat of welding
◉ When an arc is formed between two electrodes. Answer: electricity
flows from negative cathode to positive anode
◉ The magnetic pinch force helps in the process of the detaching the
molten metal drops from the electrode tip. The magnetic force. Answer:
increases as the square of the current causing smaller and smaller
droplets to be detached
◉ The electric current for welding must be transformed from. Answer:
High voltage, low amperage to low voltage, high amperage
◉ The major advantage of electron beam welding process is. Answer:
full penetration welds on thick material in one pass
,◉ The progress of welding with Electroslag welding process is. Answer:
Vertical up
◉ Explosion welding. Answer: is solid state process in which
coalescence is produced through high speed impacting of two or more
materials by controlled detonation
◉ A typical application for thermite welding is. Answer: joining of rails
◉ Welding without filler metal with GTAW process is referred to as.
Answer: autogenous welding
◉ A typical weld flaw associated with GTAW process is. Answer:
porosity
◉ SMAW power sources typically have a volt-ampere curve that is.
Answer: drooping
◉ Once a box of E49XX low hydrogen electrodes has been opened the
electrodes may remain at ambient temperature for up to a maximum of.
Answer: 4 hours
◉ Shielded Metal ARC Welding (SMAW) process. Answer: establishes
an arc between the end of a covered electrode and the work piece.
,◉ The spray mode of metal transfer is achieved with. Answer: high
amperage, high voltage and argon-rich shielding gas
◉ digital wire feeders. Answer: have feedback systems to maintain the
preset wire feed speed
◉ wire designated by CSA standard W48 as an E491T-9MJ-H8. Answer:
Results in weld deposit with a maximum of 8 ml diffusible hydrogen per
100 g of weld metal
◉ Self shield flux cored wires are. Answer: better able to tolerate air
currents
◉ The AWS classes metal cored wire along with. Answer: solid wires
◉ SAW Fluxes that significantly influence the composition of the weld
metal through slag/metal reactions are called. Answer: active
◉ Resistance welding of aluminum. Answer: Can be done but with
greater difficulty due to its low resistivity
◉ The plasma arc welding process is similar to what other welding
process in principles of operation. Answer: GTAW
, ◉ For a flat weld profile and good penetration profile using the MCAW
process. Answer: 15 degree travel angle using push technique should be
used
◉ What is the effect of tip to work distance (electrical sickout on
deposition rate of submerged are welding. Answer: decreasing tip to
work distance without adjusting any other variable will cause a increase
in deposition rate
◉ Electrode stick out is measured. Answer: From tip of nozzle to end of
electrode
◉ Contact tip-to-work is the sum (CTTW). Answer: of the electrode
extension and arc length
◉ Increasing electrical sickout. Answer: decreases voltage, decreases
current and increases resistance
◉ Which welding process for GMAW has large weld pool and is rather
large and difficult to control out of position. Answer: Spray transfer
◉ Which welding process for GMAW has excessive spatter. Answer:
Globular transfer
