A welder is attempting to perform stringer beads for a cap on a pipe in the 5G position using an E7018 electrode. They are observing issues with gravity causing the molten metal to sag and form a poor crown towards the bottom of the pipe circumference. What corrective action is most appropriate to manage the weld puddle in the changing angles of the 5G position?

Question: A welder is attempting to perform stringer beads for a cap on a pipe in the 5G position using an E7018 electrode. They are observing issues with gravity causing the molten metal to sag and form a poor crown towards the bottom of the pipe circumference. What corrective action is most appropriate to manage the weld puddle in the changing angles of the 5G position?

Answer options:

• Increase the push angle of the electrode significantly around the bottom half ✅ Decrease amperage and use a tighter arc length, particularly in the overhead sections
• Increase travel speed steadily throughout the entire circumference
• Switch to a larger diameter electrode for higher deposition

Correct answer: Decrease amperage and use a tighter arc length, particularly in the overhead sections

Explanation: In the 5G position, especially in the overhead sections, gravity pulls the molten metal down, causing sag. Decreasing amperage helps reduce the fluid nature of the puddle, making it more manageable, and a tighter arc length provides better control over the molten pool, preventing slumping. Increasing the push angle or travel speed, or using a larger electrode, would likely exacerbate the issue of sagging by either directing the heat incorrectly or increasing the volume of the molten puddle, respectively.
