Hello Pradip,

 

As mentioned below by Gerald and Dr. Georgios Dilintas(in another email) , a bake out @ 250-300 Deg C for 1-2 hrs would be advisable. The variables are :-

• section thickness(25 mm or more)
• H4 or Non H8 category of welding consumables.

If  welding is done  by GTAW (all through) then bake out may not be required at all or could be very minimal, @ 30 mins max (for mental comfort), to satisfy all  requirements.

 

Thanks.
