Question

quiz
question 6 of 8
select one way to correct excessive spatter:
increase travel speed
increase amperage
use a larger electrode
increase arc length

Explanation:

Identify the cause of excessive spatter

Using the Excessive Spatter knowledge point
Excessive spatter is often caused by an arc length that is too long (excessive voltage), which makes the arc unstable and causes molten metal droplets to scatter outside the weld pool.

Evaluate the corrective actions

Using the Arc Length Rule knowledge point
To correct excessive spatter caused by a long arc, the welder must decrease the arc length. Conversely, increasing the arc length would worsen the spatter. Increasing travel speed or amperage does not directly resolve the core physical cause of this spatter. Using a larger electrode for the same current level reduces the current density, which helps stabilize the arc transfer and reduces spatter.

Answer:

• Increase travel speed
• Increase amperage
• Use a larger electrode (Correct answer)
• Increase arc length
