Question

name this weld type.
plug weld
resistance spot weld (rsw)
gmaw or arc spot weld
slot weld

Explanation:

To identify the weld type, we analyze each option:

• Plug Weld: Involves filling a hole, but the diagram shows a spot - like weld on the surface.
• Resistance Spot Weld (RSW): Uses resistance heating but the diagram's weld shape (filled, on the surface) doesn't match RSW's typical appearance.
• GMAW or Arc Spot Weld: This type of weld is formed by an arc - based process and appears as a filled spot on the surface of lapped plates, which matches the diagram.
• Slot Weld: Involves a slot, not a simple spot as in the diagram.

Answer:

C. GMAW or Arc Spot Weld
