What is the meaning of a black flag at the intersection of the reference line and the arrow line oriented on the top side of a welding symbol?

• A. Inspection required in the field.
• B. Fillet weld to be completed in the field.
• C. Field weld on the other side of the joint.
• D. Weld to be completed in the field.

Answer: (D)

A flag at the intersection of the reference line and the arrow line is the field weld indicator. It tells you that the weld must be performed in the field (on site) rather than in the shop. The fact that it’s oriented on the top side shows which side of the joint the weld applies to, not where it’s done; the top-side placement simply designates the side of the joint, while the flag denotes field work. So the correct interpretation is that the weld is to be completed in the field. The other options don’t fit because the flag specifically marks field welding, and the side indication comes from the top/bottom positioning, not from changing the field requirement or the weld type by itself.
