Weld spatter is defined as what?

• A. Large beads
• B. Porosity
• C. Small metal droplets ejected during welding
• D. Cracks

Answer: (C)

Spatter refers to small molten metal droplets that are ejected from the weld pool during welding and land on surrounding surfaces. They do not become part of the weld bead. This happens when the arc is unstable or heat input is too high or inconsistent, and is common in processes like GMAW and FCAW. You can reduce spatter by optimizing welding parameters (adjust amperage, voltage, and travel speed), maintaining proper torch angle and stick-out, ensuring good shielding gas coverage, keeping the workpiece clean, and using anti-spatter measures. Spatter is not porosity (gas pockets in the weld) and not cracks (fractures), and it’s not the same as having large beads—the issue is those droplets being expelled from the weld pool.
