GMAW and FCAW welding are the first choice for many welding fabricators because these processes are cost effective, produce high- quality welds, and are flexible and versatile.
<u>Explanation:</u>
GMAW and FCAW utilize a spool of wire that is either housed inside the power source or took care of from an outside wire feeder. This wire or filler material is taken care of through a welding weapon.
The power source is utilized to begin and keep up the circular segment between the wire and the base metal. The welding uses strong metal wire, which requires the utilization of protecting gas to shield the weld puddle from the atmosphere.
FCAW utilizes a hollow wire loaded up with a flux powder that might require an outside protecting gas because the gas might be delivered from the flux inside the wire as it burns in the circular segment. The flux in the wire fills a large number of indistinguishable needs from the electrode coating in SMAW.
The answer is B because it could be feasible but it’s not a need it and you got a time frame but it’s not a requirement and it doesn’t have to be unique.
