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 - ANSWERA
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. - ANSWERC
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 - ANSWERB
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 - ANSWERD
The CSA W48 standard classes metal cored wires along with:
A) GMAW wires.
B) GTAW filler wires.
C) SAW wires.
D) FCAW wires. - ANSWERD
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. -
ANSWERD
The advantage of pulsed GMAW transfer is:
A) the ability to weld gauge materials with no burn-through.
