Question: 1 / 400

What happens if the arc length is too short when stick welding?

The bead width increases

When stick welding, the arc length refers to the distance between the electrode and the metal being welded. If the arc length is too short, it means that the electrode is too close to the metal. This can cause the bead width to become wider than it should be, making it difficult to achieve precise and clean welds. Option B and C are incorrect as they do not directly relate to the arc length being too short. Option B may happen if the electrode sticks for other reasons such as low current or contamination. Option C may happen due to excessive heat input or poor welding techniques. Option D is incorrect as the weld becoming brittle usually happens when the welding temperature is too high, not because of the arc length being too short. It's important to maintain the correct arc length to achieve quality welds and prevent any potential issues.
