CWB red seal review test Questions &
Answers(RATED A+)
constant current - ANSWERwhat type of power supply is required for GTAW?
decreases the current - ANSWERin a constant voltage output system, increasing tip
to work distance increases the resistance in the power circuit. What is the effect on
current flow?
rebaked at 370 to 430 degrees C - ANSWERElectrodes that are exposed to the
environment for more than 4 hours should be?
inert OR reactive gases - ANSWERthe GMAW process protects its welds through
the use of:
the 1st pass is done using a drag technique - ANSWERWhen welding the first
passes of thick groove joints with weld backing:
gas shielded penetrate more deeply than self shielded electrodes - ANSWERwhich
electrode penetrates more deeply? Gas shielded or self shielded
short-circuit transfer - ANSWERwhich GMAW transfer is most prone to incomplete
fusion?
CO2 - ANSWERWhich shielding gas may require an in line heater at high flow rates?
6-12mm (1/4 - 1/2") - ANSWERThe required electrode extension for short-circuit
transfer is:
high voltage - ANSWERTo initiate an arc requires:
EWP - ANSWERWhich of the following designates an "unalloyed" tungsten?
DCEP (reverse polarity) - ANSWERWhich GMAW polarity produces deeper
penetration?
flat and horizontal - ANSWERWhich position is SAW normally performed in?
intended for single pass only - ANSWERWhat do the letters GS mean in the
following type of electrode? ER70S-GS
Voltage-Sensing Wire Feeder - ANSWERA power supply set to constant current
mode requires a:
120v- 240v single phase - ANSWERResidential power in Canada is supplied at what
value?
