Dear Experts,
We seek your valuable insights regarding the welding, shell rolling, and dish forming processes for a clad steel reactor comprising 40mm thick SA515 Gr.60 base material with 3mm Inconel 600 cladding ( Produced by Explosion Bonding Method).
Preliminary references suggest that pre-heating may be necessary during rolling, forming, and welding operations due to the dissimilar material combination. Additionally, maintaining inter-pass temperatures between 100°C and 250°C is advised to prevent clad layer disintegration.
ENiCrFe-3 has been recommended as a suitable filler metal for both cladding and transition layer welds.
As we are new to this material combination, we would greatly appreciate expert opinions on critical considerations, best practices, and potential challenges associated with these fabrication steps.
Looking forward to your guidance.
