Which characteristic is associated with FCAW?

• A. High-deposition rate
• B. Low deposition rate
• C. No deposition
• D. Variable deposition not controllable

Answer: (A)

FCAW is known for its high deposition rate. The flux-core wire continuously provides filler metal, and the shielding is built into the core, allowing welding to proceed at higher speeds than many other processes. This means more weld metal can be deposited in a given time, which is why FCAW is favored for quickly filling and joining thicker sections. The other statements don’t fit because FCAW does deposit a lot of metal, not none, and while the exact amount can vary with wire feed speed, current, and shielding mode, you can control deposition rate rather than having it be uncontrollable.
