What type of symbol are the weld all around symbol and field weld symbols examples of?

• A. Supplementary Weld Symbol
• B. Reference Symbol
• C. Dimension Symbol
• D. Finish Symbol

Answer: (A)

Weld drawings use supplementary symbols to add extra instructions beyond the basic weld shape. The weld all around symbol shows that the weld continues around the entire circumference of the joint, and the field weld symbol indicates the weld is to be performed in the field rather than in a shop. Both of these modify how and where the welding is done, not the basic weld geometry itself, so they fall under supplementary weld symbols. Other symbols serve different purposes: a finish symbol describes post-weld finishing, a reference symbol points to notes or standards, and a dimension symbol provides measurements. Therefore, the correct type is Supplementary Weld Symbol.
