You are correct definitely we can not get El 46% but we can get YS and
TS with base metal matching by that way it will pass in TS and
naturally it will pass impact at -10 deg C so PQR will be passed.
Thank you

>Mr.Muthu,
You mean to say that the PQR when qualified should meet or exceed the
actual values mentioned in the MTC and not the minimum specified for
the base material (X65).
I think such a requirement is very unusual, you can match the strength
part, but I think its going to be a difficult task in locating a
consumable to give you 46% elongation.
Wish you good luck!

Praveen
