Dear Kalimuthu,
You can use the consumable for 1-1/4Cr-1/2Mo (LAS) to weld LAS # CS. The issue will be PWHT. The joint welded with this consumable will need to undergo PWHT at temperature of LAS (which is higher than CS - 650C).
Check with Design people as sress considered for E309 would be lower than the P11 hence the strength would not be suffecient enough. Even if you weld with E309 and test tensile to qualify PQR you may achieve the UTS (UTS shall be at least equal to lowest of the two).
To achieve the Strength you need to use inconel grade consumable which can avoid PWHT of this joint and can avoid strength problem as well. But again as it is high temperature service. Expansion to be considered.
With above inputs try to work out suitable option for your usage.

Dear All,Here in our project we have A106 GR B to A335 P11 Dissimilare welding ,Can any on suggest the filler wire and Electrode?Is it possible to use ER309 and E309.RegardsMano
