How can you tell a weld is meant to be performed in the field based on the welding symbol?

• A. The symbol includes a field weld indicator (flag) or field note specifying field work
• B. The symbol includes a note about post weld heat treatment
• C. The symbol specifies the welding filler metal type
• D. The symbol uses a dashed line

Answer: (B)

You tell a weld is meant for the field by looking for a field indicator on the welding symbol. If there’s a field weld indicator (a small flag) on the symbol or a field note attached, that explicitly designates the weld as must be done in the field. A note about post weld heat treatment describes what happens after welding, not where the weld is performed, so it doesn’t indicate field work. The filler metal type tells you what material to use for the weld, not where to perform it, and a dashed line isn’t the marker for field work. So the presence of a field weld indicator or a field note is the correct cue that the weld is intended for the field.
