Question: What is spatter in welding and how can it be primarily reduced in GMAW?
Answer options: ✅ Molten metal droplets expelled from the weld pool; reduced by optimizing voltage and wire feed speed
- Excessive penetration; reduced by increasing travel speed
- Lack of fusion; reduced by increasing current
- Surface oxidation; reduced by increasing shielding gas flow
Correct answer: Molten metal droplets expelled from the weld pool; reduced by optimizing voltage and wire feed speed
Explanation: Spatter consists of small molten metal particles ejected from the arc, which can adhere to the workpiece. In GMAW, spatter can be significantly reduced by proper adjustment of voltage and wire feed speed, which together control the arc length and transfer mode.
