The door is 1/2 thick Inconel plate, the final surface is to be Lead(pb) but the intermediate material is not speced. The normal process is to grind a clean surface on the ferrous metal then apply a lead bearing flux, usually a mixture that includes zinc and copper heat till glossy then wipe...
I need to bond lead to Inconel? Is this possible? One method I thought about trying is to bond a second metal to the Inconel then bond the Lead(pb) to that> But what would be the steps fluxs and the like?
