Spray transfer produces high deposition rates.

• A. True
• B. False
• C. Low deposition rates
• D. No deposition

Answer: (A)

Spray transfer moves metal from the wire to the weld puddle as a continuous spray of many tiny droplets. Because the metal is transferred in a steady, uninterrupted stream, a large amount of weld metal can be deposited each second, giving a high deposition rate. Deposition rate is simply how much weld metal is deposited per unit time, and with spray transfer that rate is high when parameters are set for a stable spray (high welding current, appropriate shielding gas, right wire size, and suitable travel speed). This mode is favored when you want fast, smooth deposition, though it comes with higher heat input and is less ideal for very thin sections or certain positions. So the statement is true.
