The ____ symbol indicates that the same type weld joint is to be used on all continuous edges of a box or cylindrical part.

The ____ symbol indicates that the same type weld joint is to be used on all continuous edges of a box or cylindrical part.

• A. Weld-all-around
• B. Weld-all-round
• C. All-around
• D. Perimeter weld

Answer: (A)

All-around is the key idea. In welding symbols, an all-around weld means the joint is welded continuously around the entire perimeter, so for a box or cylindrical part the same weld type is applied on every continuous edge around the part. This ensures uniform strength and sealing around the whole joint. The label used for this concept is typically "Weld-all-around" (often written as all-around), which is why that option fits best. Terms like "perimeter weld" can be misleading because they imply just the outline, not a full circumferential weld, and variants like "all-round" are just spelling differences.
