RE: [MW:4034] Impact

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 ????
