Hello Experts,

I have query regarding use of Cu Ni 90/10 consumable for overlay  with support of Cu Ni 70/30 weld overlay procedure  qualification or I will have to qualify new procedure with use of CU/Ni 90/10 consumable.

Regards,
Mohit.

For welding barrier layer of Clad steel it is recommended to use 65% Nickel-copper(Monel) filler Rod / Electrodes & remaining overlay may be welded using 70-30 Cu-Ni or 90-10 CuNi electrodes accoring to the requirements. 

Please see snap shot below.
