ASME B16.25 specifies the end preparation for which weld feature?

• A. Pipe end chamfer
• B. Weld end details
• C. Groove weld dimensions
• D. Weld end preparation

Answer: (D)

The question tests understanding of what end preparation means in the context of welded flange joints. ASME B16.25 focuses on welded pipe flanges and the joints that join them, and it specifies how the ends of the components that will be welded are prepared to form the joint. This “end preparation” refers to shaping the pipe and flange ends (such as beveling or chamfering) so that a proper weld can be made, with the right groove geometry and ability to fuse the materials effectively. In this sense, the standard is specifying the weld end preparation—the preparation applied to the ends before welding—rather than broader details like general pipe end chamfers, groove weld dimensions, or other weld details.
