What step follows measuring and determining clearance in silver brazing preparation?

The step that logically follows measuring and determining clearance in silver brazing preparation is to round the pipe end with an expander. After ensuring that the measurements and clearances are accurate, it's important to prepare the end of the pipe for optimal joint fit. This preparation often involves making the end of the pipe smooth and round, which can facilitate a better connection and help in achieving uniform heating during the brazing process.

Rounding the pipe end creates a more consistent surface that can be easier to join effectively when applying the brazing alloy. A well-prepared surface contributes to the overall integrity and quality of the brazed joint.
