For a plug weld, where is the depth of filling indicated on the welding symbol?

• A. Left of the weld symbol.
• B. Below the weld symbol.
• C. On the right side of the weld symbol.
• D. Inside the weld symbol.

Answer: (D)

The depth of filling for a plug weld is shown inside the plug weld symbol. This placement keeps the fill-depth measurement directly with the plug’s geometry, separate from the hole diameter or the weld’s location on the joint. Reading it inside the symbol makes it clear how deep the weld material should extend into the hole area, which is the crucial dimension for a plug weld. Other placements would confuse the parameter with the hole size, side of the joint, or their other positional notes, so the symbol itself carries the fill-depth information where it belongs.
