bead e
bead a
bead f
bead d
bead c

Explanation:

Analyze the 2G weld pass sequence

Using the 2G Weld Sequence and Horizontal Groove Welding knowledge points

In horizontal groove welding (2G position), multi-pass welds are deposited in a specific sequence to prevent sagging and ensure proper fusion:

1. First Pass (Root Pass): Bead A is placed at the root of the joint.
2. Second Pass: Bead B is placed along the upper bevel of the joint.
3. Third Pass: Bead E is placed below Bead B to support it and fill the lower portion.
4. Fourth Pass: Bead C is placed at the top of the next layer along the upper plate.
5. Fifth Pass: Bead F is placed directly below Bead C to continue filling the joint.
6. Sixth Pass: Bead D is the final cover pass at the bottom.

Therefore, the fifth pass corresponds to Bead F.

Answer:

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