Welder Red Seal · Question
A structural welder is performing overhead FCAW-G on 12 mm (0.5 in) thick steel with an E71T-1 wire. The weld appears saggy and excessively convex, despite the welder trying to maintain a short arc. What is the most likely adjustment needed?

Question: A structural welder is performing overhead FCAW-G on 12 mm (0.5 in) thick steel with an E71T-1 wire. The weld appears saggy and excessively convex, despite the welder trying to maintain a short arc. What is the most likely adjustment needed?
Answer options:
- Increase stick-out.
- Increase wire feed speed. ✅ Decrease voltage.
- Increase shielding gas flow rate.
Correct answer: Decrease voltage.
Explanation: A saggy, excessively convex weld, especially in overhead positions, often indicates that the voltage is too high, leading to a fluid puddle that is difficult to control. Decreasing the voltage will help the puddle to stiffen and gain better contour. Increasing wire feed speed without adjusting voltage would make the puddle even more difficult, and increasing stick-out promotes a colder weld.
