Hello prasad,
No need to do ferrite testing for SA 312 TP 316 L Welding, because this all are austenitic stainless steels.
Ferrite testing is applicable for Duplex stainless steel because it is a ferritic steels.
For SA 312 TP 316 L Welding procedure you have to do IGC practice E or it may as per client requirements.
If any thing wrong, I am apologies for the same.
Regards,
Rajendra
