Spray transfer in GMAW typically results in which characteristic compared to short-circuit transfer?

• A. Spray transfer provides higher deposition with smoother beads.
• B. Spray transfer deposits less metal.
• C. Spray transfer is never used on thicker sections.
• D. Short-circuit transfer requires no clean surfaces.

Answer: (A)

Spray transfer delivers metal in a continuous spray of many tiny droplets, transferred at higher current and with the right shielding gas. That setup yields a high deposition rate and a very smooth, uniform weld bead with good fusion. That’s why the description of spray transfer as providing higher deposition with smoother beads is the best fit. The other statements aren’t accurate: spray transfer does not deposit less metal, it can be used on thicker sections under the right conditions, and cleaning surfaces is still important for any welding process.
