Calling out groove weld size on drawings Is the size of a groove weld (e.g., effective throat, depth of bevel or penetration) typically specified directly on the welding symbol?

Introduction / Context:
Drawings must convey exactly how much weld metal and fusion is required. For groove welds, size is critical to strength and cost. Standards provide a concise way to indicate these requirements on the symbol itself.

Given Data / Assumptions:

• We are specifying a groove weld (e.g., V, U, J, bevel, square).
• Symbol placement follows standard conventions.
• Dimensions such as depth, root opening, and effective throat may be needed.

Concept / Approach:
Welding symbols accommodate size information adjacent to the basic symbol: depth of bevel or penetration is given to the left of the symbol, root opening and groove angle can be called out, and supplementary notes define backing, surfacing, or multiple passes. This allows the fabricator to reproduce the required geometry and performance.

Step-by-Step Solution:

Verification / Alternative check:
Compare example tables in welding symbol standards; they show groove sizes annotated directly on the symbol.

Why Other Options Are Wrong:
General notes alone are insufficient for specific joints; groove size is not limited to fillet welds and is independent of contour symbols.

Common Pitfalls:
Confusing effective throat with leg size for fillets, omitting root opening, or placing dimensions on the wrong side of the reference line.

Final Answer:
Correct
