100
What is groove welds
This category of welds includes edge preperations such as U's, J's, and V's.
200
What is flat and horizontal
What positions are weld able with the electrode e-6022?
200
What is .025" , .035" , .045" , and .052" wire diameters.
GMAW and FCAW welding wire comes in what sizes?
200
What is Heat Treating
_____ _______ of steel and other metals can lead to improved wear resistance, increased resistance to warpage and deformation, and increased strength and toughness.
200
What is Lap, Tee, Butt, Edge, and Corner
What are the five types of Welding Joints?
300
What is DCEP
What is the correct polarity for running an e-7018 electrode?
300
What is FCAW-SS
FCAW can be divided into two categories: self shielded (FCAW-SS) and gas-shielded (FCAW-G). If inner shield FCAW does not require and auxiliary cylinder, is it FCAW-SS or FCAW-G?
300
What is hot rolling
There are various methods of forming steel into finished products. Including hot forging, hot and cold rolling, seamless tube making and welded tube making. The most widely used process is __ _____, which accounts for over 90% of all steel production.
400
What is 60,000 lbs/sq inch
What is the tensile strength of an e-6010 electrode?
400
What is Both GMAW and FCAW can use this Carbon Steel fill and shielding gas.
AWS wire classification ER70S-6, and the combination of shielding gas 25% Co2 - 75% Ar, is compatible with only GMAW, only FCAW, or compatible with both?
400
What is hot forging
___ _____ heats the work piece to a malleable temperature (a temperature where the metal becomes easier to shape) or to the point where work hardening no longer occurs.
500
What is the Flux composition
What does the last digit of an electrodes' number stand for?
500
What is Contact to Work Distance (CTWD)
There are four main variables of the GMAW process that affect both the penetration profile into the base material and weld bead profile that lies above the base material for a given weld: A) Welding Current B) Welding Voltage C)__________ and D)Travel Speed
500
What is cold forging
____ forging deforms metal while it is below its recrystallization point. ____ forging is generally preferred when the metal is already a soft metal, like aluminum. This process is usually less expensive and the end product requires little, if any, finishing work.
