Joint details in a WPS are often presented how?

• A. On an attached sketch
• B. In the text only
• C. In a separate certificate
• D. In a code table

Answer: (A)

Visual representation matters because the geometry of a weld joint is spatial and easy to misinterpret in words alone. An attached sketch provides the exact groove type, bevel angle, root opening, weld size, fit-up, and plate orientation the welder must work to. This drawing acts as a clear, unambiguous reference that complements the procedural details in the WPS, helping ensure the joint is prepared and welded to the correct geometry and that inspectors can verify it against the drawing.

Describing joint details only in text can lead to misreadings of angles, gaps, or clearances. A separate certificate is about qualification records, not the joint geometry for a specific weld. A code table might give standards or allowed values, but it won’t convey the precise joint configuration for a particular weld in the project context.
