CWB LEVEL 2 VISUAL WELD INSPECTOR
EXAM 2025 UPDATED ACTUAL EXAM WITH
CORRECT SOLUTIONS.
A consumable electrode is: - correct answer- AN electrode
which melts and provides metal to fill the joint
The weld heat affected zone is: - correct 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 - correct
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 - correct 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 -
correct answer- High voltage, low amperage to low voltage,
high amperage

The major advantage of electron beam welding process is -
correct answer- full penetration welds on thick material in one
pass
The progress of welding with Electroslag welding process is -
correct answer- Vertical up
Explosion welding - correct 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 - correct answer-
joining of rails
Welding without filler metal with GTAW process is referred to as
- correct answer- autogenous welding
A typical weld flaw associated with GTAW process is - correct
answer- porosity

SMAW power sources typically have a volt-ampere curve that is
- correct 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 - correct answer- 4 hours
Shielded Metal ARC Welding (SMAW) process - correct
answer- establishes an arc between the end of a covered
electrode and the work piece.
The spray mode of metal transfer is achieved with - correct
answer- high amperage, high voltage and argon-rich shielding
gas
digital wire feeders - correct answer- have feedback systems to
maintain the preset wire feed speed
wire designated by CSA standard W48 as an E491T-9MJ-H8 -
correct 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 - correct answer- better able to
tolerate air currents
The AWS classes metal cored wire along with - correct answer-
solid wires
SAW Fluxes that significantly influence the composition of the
weld metal through slag/metal reactions are called - correct
answer- active
Resistance welding of aluminum - correct 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 - correct answer-
GTAW
For a flat weld profile and good penetration profile using the
MCAW process - correct answer- 15 degree travel angle using
push technique should be used
