Cleaning is required after welding. However, we need to find if the
welded area is subjet to corrosion. I feel that if welded area needs
corrosion resistance, then electrodes for inconel welding may be
abetter option, as it improves corrosion resistance of weld area. The
working temperature and operating environment in weld zone will be
important.

Dear hMr. Bagchi
I attached our drawing, do you mean after completion of welding there
is no cleaning required?

Dear Mr. Himan,
Normally, Inconels are higkly corrosion resistant alloys, which do not
need passivation. However, you are advised to show assemby drawing near
welded area which needs to be looked into.

overlaied by Inconel, I want to know we shall clean welded separate
