Question

identify where to place the second pass for this 4g weld.

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

Explanation:

Analyze the joint geometry and position

The image shows a multi-pass groove weld in the overhead position (4G position). The horizontal plate is on top, and the vertical/slanted plate is on the right, forming a groove joint welded from underneath.

Identify the first pass (root pass)

Using the Multi-pass Welding knowledge point, the root pass is placed deepest in the joint to fuse the two members together. In the provided diagram, the first bead placed at the root of the joint is labeled A.

Determine the sequence for the second pass

In multi-pass overhead groove welding, after the root pass (Bead A), subsequent passes are layered systematically to build up the weld. The second pass (Bead B) is placed directly adjacent to the root pass, typically along the vertical/slanted member to provide a shelf and support subsequent passes. Looking at the diagram, the bead labeled B is positioned directly next to Bead A.

Match with the options

The question asks to identify where to place the second pass for this 4G weld. The second pass is Bead B.

Answer:

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