Gouging produces a V-shaped groove.

Gouging produces a V-shaped groove.

• A. True
• B. False
• C. It produces a U-shaped groove
• D. It produces a rectangular groove

Answer: (B)

Gouging uses a high-energy arc to melt and remove metal, and the molten metal is often blown away by the arc jet. This interaction tends to create a groove with a rounded bottom and curved walls, not a sharp, pointed V. The natural cross-section is more like a U-shaped groove, with the bottom formed by the deepest melting and the sides flaring outward from the arc’s effect. A rectangular groove would require very flat, straight-edged walls that gouging doesn’t typically produce. So, saying gouging produces a V-shaped groove isn’t accurate; the common result is a U-shaped groove.
