Merely buffing will worsen the condition, it may give us a bright look immediately after buffing, but sooner or later we can able to see a uniform rust all around the weld joints.
In picking and passivation is not in the scope of work, and no painting system is applicable for those lines, from integrity point of view, it is highly recommended to carry out picking and passivation.
The situation will still go worse if the system is going get operated in high humidity environment, like sea-shore, offshore etc.
Anyway, the final call is with the client.

Dear experts,
For after weld cleaning of SS weld joints my client insisted to do buffing on all the joints.
1. Is it a good suggestion?
2. Is there any technical argument so that we can avoid it?
3. Will buffing remove the passive layer and promote corrosion?
4. I got a comment that Buffing is a pickling activity and it should follow the preparation of not better not to go for buffing.
Presently we are cleaning the joints with SS wire brush after welding.
We don't have pickling and application in the scope of work and no need to for the same.
Thanks in advance.
