16.
To eliminate undercutting using the weaving technique stop
momentarily at the end of each motion.
17.
In FCAW, the flux inside the tubular wire contains ingredients that
provide shielding.
18.
The FCAW process has the capability of being used in all
positions.
19.
FCAW-G indicates Gas shielded.
20.
Of the two basic FCAW processes, one is self shielded, and one
uses an external shielding gas.
21.
A Knurled type of drive rollers should be used with FCAW
electrode wires.
22.
Welding in windy areas is not an advantage of the FCAW process.
23.
The process does not produce slag free welds.
24.
When examining a spool of FCAW wire to determine if it is
designed for flux core welding, one should look for A T in the electrode
classification designation.
25.
A flux cored electrode used with an external shielding gas is not
self shielded.
26.
In the FCAW classification E71T-1 the letter T indicates tubular
electrode.
27.
External shielding gas is not essential for FCAW-S.
28.
E71T-5 electrode classification identifies a filler metal that can be
used in the overhead position.
29.
A flux cored electrode that protects the weld zone from
contaminates with fluxing elements released from the core of the wire
itself is called self shielded.
30.
In the AWS classification E71T-1, the digit after the dash
designates chemical composition.
