suggestion
increase the preheat to minimum of 150 deg C

Interpass max- 150C
heat input for weld overlay is max. 1.38 KJ/ mm
we did PT examination at different cross section, but can not find defect at fusion line.
Cr in inconel 600 is higher than in low alloy steel, during welding process particularly in fusion zone, the diffusion of Cr and Ni occur from inconel 600 into low alloy steel at the fusion zone and form the thin film which has high Ni and Cr content. An increase of the Cr and Ni content at fusion zone would raise the tendency for the martensite formation as shown by Schaffler diagram.
If this is true as per attached research paper then how to solve this problem?
