Dear Amarjeet
With c3 it is bit difficult to get Impact at minus 60 C after PWHT of 620 C for 5 hrs (generally ask 2 Cycles0
Welding in 3 G
You can get with Honavar or Thysen brand of 8018C1/C3 but with interpass of 150C withPWHt of 600-610max for 2hr

Dear Mr. Amarjit singh,
E 7018 C3 L electrode is OK. You will get impact propery with this electrode with out PWHT also. I have done a procedure with this elcetrode and without impact test at -54 deg. C.
Thanks & Best Regards.
John.

Dear all,
I am facing the problem of impact test at -60 deg C in welding.
The material is SA 537 Cl 1 and welding consumable used is E7018 C1L ( Advani make). as C1L contain Ni its weld should pass impact but the same is not. where as impact is OK with E-7018 C3L electrodes.
can any body suggest ????
