CWB red seal review test
constant current - Answer-what type of power supply is required for GTAW?
decreases the current - Answer-in 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 - Answer-Electrodes that are exposed to the environment for more
than 4 hours should be?
inert OR reactive gases - Answer-the GMAW process protects its welds through the use of:
the 1st pass is done using a drag technique - Answer-When welding the first passes of thick groove joints
with weld backing:
gas shielded penetrate more deeply than self shielded electrodes - Answer-which electrode penetrates
more deeply? Gas shielded or self shielded
short-circuit transfer - Answer-which GMAW transfer is most prone to incomplete fusion?
CO2 - Answer-Which shielding gas may require an in line heater at high flow rates?
6-12mm (1/4 - 1/2") - Answer-The required electrode extension for short-circuit transfer is:
, flat and horizontal - Answer-Which position is SAW normally performed in?
intended for single pass only - Answer-What do the letters GS mean in the following type of electrode?
ER70S-GS
Voltage-Sensing Wire Feeder - Answer-A power supply set to constant current mode requires a:
120v- 240v single phase - Answer-Residential power in Canada is supplied at what value?
high voltage - Answer-To initiate an arc requires:
EWP - Answer-Which of the following designates an "unalloyed" tungsten?
DCEP (reverse polarity) - Answer-Which GMAW polarity produces deeper penetration?
constant current - Answer-Which type of power is best suited for manual welding?
composite filler metal - Answer-What does the letter C stand for in the following type of electrode?
ER70C-X
pure tungsten using AC - Answer-Which tungsten would you expect to see balled after striking an arc?
high current - Answer-Excessive spatter and undercutting of a weld bead can be caused by:
increase arc voltage - Answer-To increase arc length when SAW welding:
