What are used in a welding symbol to show additional information such as field weld or weld all around?

• A. Supplementary symbols
• B. Primary symbols
• C. Weld standards
• D. Tolerance marks

Answer: (A)

Supplementary symbols are the extra details added to a weld symbol to convey information beyond the basic weld type. They tell the welder how the weld should be performed in specific circumstances, such as being done in the field or running all the way around the joint. For field welds, a FIELD indication (often placed in the tail or with a leader) flags that the weld must be completed at the job site rather than in the shop. For welds required all around, a circular indicator around the weld symbol communicates that the weld continues around the joint circumference. The main, primary weld symbol shows the type of weld, while supplementary symbols provide these additional instructions. Other options refer to the weld’s shape, the standards to follow, or tolerances, none of which convey the extra field or all-around details.
