You should go to a super austenitic filler metal which is going to provide higher ductility. What is the working environment of the weld?

Dear Sirs,

Greetings !

We are in process to perform WPS/PQR for SS446 to SS446 combination.

Welding done on 20 mm thick plates using ER430 filler.

Test coupon passed for Tensile test but it is getting failed in Bend test .

Need your expertise opinions /suggestions  to complete this WPS/PQR with satisfactory results as per requirements of ASME Section IX .

Especially guidance  to pass Bend test .

Thanks in Advance

Regards
