Question

identify the type of weld and position.
○ plug weld (flat)
○ none of these
○ plug weld (vertical)
○ slot weld (flat)

Explanation:

A plug weld is a circular weld (as seen in the diagram), and the flat position implies the weld is done on a horizontal, flat surface. The diagram shows a circular (plug - like) weld in a flat - oriented joint (the zig - zag edges suggest a flat - placed joint context), so it's a Plug weld (Flat).

Answer:

A. Plug weld (Flat)
