Question

identify where to place the second pass for this 2g weld.

bead c
bead e
bead a
bead f
bead d
bead b

Explanation:

Understand the 2G welding position

Using the Horizontal Groove Welding knowledge point
In a horizontal groove weld (2G position), gravity pulls the molten weld pool downward. To prevent sagging and ensure proper fusion, a specific multi-pass sequence is used.

Analyze the bead sequence

Using the 2G Weld Sequence knowledge point
The root pass is Bead A, placed deep in the joint. For the second pass, the bead is placed on the bottom side of the groove to create a shelf that supports subsequent passes. Looking at the diagram, Bead E is positioned at the bottom of the second layer, directly supporting Bead B above it. Therefore, the second pass is Bead E.

Answer:

• Bead C
• Bead E (Correct answer)
• Bead A
• Bead F
• Bead D
• Bead B
