1. How many layers deposited with thickness of each layer including barrier layer?
2. Check for Welding consumable chemistry used for welding (Batch No wise).
3. Max Ni content for SS410 for FCAW Consumable is 0.6%. Hence, depends upon your consumable batch no, the chemistry will be achieved. We can’t get 0.6% Ni because of variation in batch no.
4. ‘’C’’ content. Again it is depends upon the batch used. Check for the same.
5.

Dear all
I have problem in the overlay of SS 410 on SA 516 Gr 70 with FCAW
process
- I am unable to achieve the carbon % 0.06
- failure in bend test
- unable to achieve Ni content of 0.6%
As required the barrier layer of E309Lmo which contains high value of
Ni and Cr .
Please let me know is it possible to achieve 0.6% Ni in clad layer
with height of 6mm only.
how to clear the bend test ? or waiver from client is the only option.
Looking for you valuable suggestions.
