I have qualified wps for sa 335 P5 to SS 317L of full TIG of ER NiCr 3 with PWHT.
My query is that when I will do PWHT for the joint will it not sensitized the SS material?
Buttering is one method to avoid this condition ,
How we avoid sensitizetion in ss material after welding in field joint which are not stabilized grade?
And also in case of stabilized grade after solution anealling we are not doing heat treatment for field joint.
Will it not sensitized the joint?
Please help me in this query.
Thanks
Sunil
