Which type of weld is performed at the location of the joint rather than in a shop?

• A. Finish
• B. Weld All Around
• C. Field Weld
• D. Tail

Answer: (C)

Welding by location is the key idea here: field work is done at the job site, not in a shop. A field weld is performed where the joint sits—in the field—using portable equipment and procedures suited to on-site conditions. This is common when components are too large to move, or when assembly must happen in the structure’s final position. Field welding also involves adapting to outdoor conditions, ensuring proper preheat and heat control, and following field welding procedures and codes.

The other terms don’t specify where the weld takes place. A finish weld refers to the final pass to smooth or complete a joint, Weld All Around describes a circumferential weld around a part, and Tail isn’t a standard term for a weld type.
