Where are dimensions for preparation of groove welds indicated in relation to the weld symbol?

Dimensions for the preparation of groove welds are indicated on the same side of the reference line as the weld symbol itself. This is a standard practice in welding print reading, as it helps to clearly communicate the required dimensions for the weld preparation directly associated with the weld symbol. Positioning the dimensions on the same side fosters a clear understanding for the welder or fabricator, showing exactly what is needed for proper execution of the groove weld.

For reference, indications placed above or below the reference line typically pertain to specific parameters or details that are separate from the actual dimensions of the weld preparation, often relating to the weld type or size, rather than the groove preparation dimensions. Thus, ensuring that preparation dimensions are aligned with and on the same side as the weld symbol maintains clarity in the design and ensures that anyone reading the print can easily identify the relevant dimensions without confusion.
