?How does the flux in a FCAW wire compare to a SMAW electrode and what does it affect?
A. ?FCAW has less flux but the wire is fed into the weld faster so there is more slag on a weld as compared to a SMA weld.
B. ?Both processes' filler metals have the same amount of flux, but only the FCAW flux gets pushed deeper into the molten weld pool.
C. ?FCAW wire has a lower flux to metal ratio so it is more efficient than SMAW.
D. ?SMAW filler rods are a lot bigger than FCAW wire but there is more flux to filler metal in the FCAW filler wire.
