“Usual” fillet weld geometry In standard drafting practice, is a typical (default) fillet weld assumed to have equal legs unless otherwise specified on the symbol or in notes?

Introduction / Context:
Fillet welds join surfaces roughly at right angles. Their size is commonly expressed as the leg length or the effective throat. When not further qualified, drawings and symbols often imply a symmetric fillet (equal legs), simplifying communication.

Given Data / Assumptions:

• No unequal leg designation is shown (e.g., no a×b notation).
• Standard fillet weld symbol is used without special modifiers.
• Material, position, and process do not inherently dictate unequal legs.

Concept / Approach:
The default interpretation in many drafting standards is an equal-leg fillet when only a single size value is provided. If unequal legs are needed for load or fitment reasons, they must be explicitly called out (e.g., 6×8) with orientation clarified relative to the joint members.

Step-by-Step Solution:

Verification / Alternative check:
Review examples in welding symbol guides showing equal-leg assumptions unless otherwise specified.

Why Other Options Are Wrong:
Leg equality is not restricted by weld position, alloy, or continuity pattern.

Common Pitfalls:
Misreading leg size vs throat size, failing to orient unequal legs correctly, and assuming the larger member always receives the longer leg without notation.

Final Answer:
Correct
