In a WPS, which element is described by grooves, angles, root face dimensions, and root spacing with tolerances?

• A. Joint details
• B. Backing strip
• C. Weld passes
• D. Shielding gas

Answer: (A)

Joint details describe how the joint is prepared and fit up. In a WPS, this includes the groove type, bevel angles, root face width, and the root spacing (gap) with tolerances. These geometric features determine how the parts will fuse at the root, control penetration and reinforcement, and ensure consistent weld quality despite small variations during welding. The groove geometry sets the access for the weld, the bevel angle and root face influence how much material must be melted, and the root spacing affects root penetration and defect risk. The tolerances specify how much deviation from the nominal geometry is acceptable to still meet the required weld performance. Other elements like backing strip, weld passes, or shielding gas relate to different aspects of the welding setup rather than the joint geometry itself.
