FCAW Final Exam Questions with Correct Answers Latest Update 2025/2026
True - Answers Tubular electrodes are used for FCAW.
False - Answers A typical electrode extension for self-shielded electrodes ranges from 1/4" to 1
3/4".
True - Answers FCAW-G commonly uses carbon dioxide as a shielding gas.
True - Answers Some flux cored electrodes can be used without the addition of a shielding gas.
False - Answers FCAW welding most commonly uses AC current for flat position.
True - Answers For FCAW, welding current is adjusted by increasing or decreasing the wire feed
speed at the wire feeder.
False - Answers The FCAW-S process requires a shielding gas from an external source.
True - Answers Gas flow rates can range from 30cfh to 45 cfh.
True - Answers FCAW produces less distortion than SMAW as well as smooth, uniform beads.
False - Answers The T in the electrode classification for flux cored electrodes means that the
electrode is tough.
True - Answers Too much drive roll tension can collapse tubular electrodes, so FCAW uses
knurled drive rolls.
False - Answers When using the Z-weave technique for FCAW, move up the joint in large
increments, and stop momentarily at each toe to prevent undercut.
tubular electrode - Answers Unlike GMAW, FCAW uses a ___ with flux in its core.
tubular - Answers Flux cored electrodes are ___ electrodes.
FCAW-S - Answers A gaseous shield created by the tubular electrode protects the weld area in
the ___ welding process.
acid - Answers A(n) ___ slag system is a slag system that promotes spray transfer with low
spatter and fast-freezing slag.
direct current; CV - Answers FCAW uses a(n) ___;___ welding power source.
wire feed speed - Answers The higher the ___, the higher the welding current.
FCAW-S - Answers In the ___ process, shielding gas is provided exclusively by the flux core
within the electrode.
Fume extraction - Answers ___ equipment should be used to keep smoke and fumes from
