Dear Sirs
Appreciate detail guidance.

Honestly i never did pay attention to it!

Welded Joint Surface Roughness Acceptance shall be in conformance with Symbol J

J Surface roughness ≤ 500 min. Surface Rougness(Ra) in accordance with ASME B46.1
(6) Where two limiting values are separated by “and,” the lesser of the values determines acceptance. Where two sets of values are separated by “or,” the larger value is acceptable. T w is the nominal wall thickness of the thinner of two components joined by a butt weld.

1- How to measure and evaluate?
2- Welding Inspector qualified to perform Roughness Measurement?
