Question

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

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

Explanation:

Analyze the 2G weld sequence

Using the 2G Weld Sequence and Horizontal Groove Welding knowledge points
In a multi-pass horizontal groove (2G) weld, gravity affects the weld pool, requiring a specific sequence to build up the joint properly.

• Pass 1 (Root): Bead A is placed at the root of the joint.
• Passes 2 & 3 (Fill): Bead B is placed along the bottom edge of the groove, and Bead C is placed above it to complete the second layer.
• Passes 4, 5 & 6 (Cap/Fill): The third layer is built from the bottom up. Bead D is placed along the bottom edge, Bead E is placed in the middle, and Bead F is placed at the top to complete this layer.

Identify the sixth pass

Using the 2G Weld Sequence knowledge point
Looking at the diagram and the standard bottom-to-top progression for each layer:

• Layer 1: Bead A (1st pass)
• Layer 2: Bead B (2nd pass), Bead C (3rd pass)
• Layer 3: Bead D (4th pass), Bead E (5th pass), Bead F (6th pass)

Therefore, the sixth pass corresponds to Bead F.

Answer:

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