Meaning of the arrow in a welding symbol On a standard welding symbol, does the arrow indicate the specific joint (location) where the weld is to be made?

Introduction / Context:
Welding symbols consist of an arrow, reference line, and optional tail. Correct interpretation of the arrow is essential for placing the weld on the right joint and on the correct side (arrow side or other side) relative to the reference line.

Given Data / Assumptions:

• Standard symbol conventions (AWS/ISO) are used.
• The symbol shows a weld type, size, and possibly side designation.
• The arrow touches or clearly indicates a joint edge.

Concept / Approach:
The arrow identifies which joint the symbol applies to. The positioning of the symbol element (below or above the reference line in AWS, or specific side indicators in ISO) designates whether the weld is on the arrow side, the other side, or both sides. The arrow itself is not a process indicator; the tail may carry process notes if needed.

Step-by-Step Solution:

Verification / Alternative check:
Compare multiple joints in a complex assembly; the arrow unambiguously selects which joint the symbol governs.

Why Other Options Are Wrong:
The arrow does not denote process; the tail can. It does not always point to the “opposite member,” and it is used for all weld types, not only intermittent patterns.

Common Pitfalls:
Misreading arrow-side vs other-side conventions and overlooking supplementary symbols.

Final Answer:
Correct
