CWB Level 1 Inspector -Welding Process and
Equipment (1) (solved &
updated)
When an arc is formed between two electrodes:
A) electricity flows from the negative cathode to the positive anode.
B) electricity flows from the positive cathode to the negative anode.
C) electricity flows at random between the anode and cathode.
D) electricity stops flowing once the arc is established
A
The SAW fluxes are:
A) classified on their own. They have their own separate designation.
B) not classified. Only the wire is classified.
C) classified in conjunction with the welding wire forming an electrode/flux
designation.
D) all classified with EM12K wire. Use of other wires would require companies to
perform testing to verify desired properties.
C
The CSA W48 standard classes metal cored wires along with:
A) GMAW wires.
B) GTAW filler wires.
C) SAW wires.
D) FCAW wires.
D
The submerged arc welding process:
A) can only be used with a constant voltage power supply.
B) can only be used with a constant current power supply.
C) can only be used with a constant current power supply with high frequency.
D) can be used with either a constant voltage or constant current power supply.
D
The advantage of pulsed GMAW transfer is:
A) the ability to weld gauge materials with no burn-through.
B) reduced heat input.
C) less operator skill is required.
D) increased productivity.
B
, What is the weld called when no filler is added while using the gas tungsten arc
welding process?
A) Surface weld
B) Automatic weld
C) Braze weld
D) Autogenous weld
D
The SAW fluxes that significantly influence the composition of the weld metal
through slag/metal reactions are called:
(A) fused
.B) bonded.
C) active.
D) neutral.
C
What are examples of an F3 fast-freeze SMAW electrode?
A) EXX15, EXX16, EXX18
B) EXX10, EXX11
C) EXX12, EXX13, EXX14
D) EXX22, EXX24, EXX27, EXX28
B
The GMAW process uses __________ to shield the molten weld metal from the
atmosphere:
A) a slag system
B) a blanket of flux
C) a vacuum chamber
D) an external shielding gas
D
Examples of physical properties that influence the GMAW arc are:
A) flow rate, temperature range, and density.
B) radiation potential, thermal expansion, and weight.
C) ionizing potential, thermal conductivity, and specific density.
D) ionizing potential, thermal conductivity, and specific gravity.
D
Which of the following processes uses a non-consumable electrode?
A) SAW
B) SMAW
C) GTAW
D) GMAW
C
When using the SMAW process, what are some of the functions of the flux?
A) Shield the arc and molten metal, stabilize the arc, control the weld metal
chemistry, and provide a slag coating.
B) Shield the arc and molten metal, provide identification for the electrode, and
