Inconel Inlay Cladding

admin

Hi there, could someone here help to explain what is INCONEL INLAY CLADDING?Normally where is it applied (which Industires) and why?What is the significant advantages over other welding?Any idea about the investment and skills required?Thanks a lot.Tom Long
Reply:Correct me if Im wrong but Inconel cladding is just welding inconel to a piece of usually cheaper metal (like CS) to save money instead of making the whole piece out of the more expensive metal. At my old work we used to have tons of nickel clad process vessels that were just CS tanks with thin nickel plate welded to the internals of the process vessel, and anywhere that the actual chemical would touch (like on the manway covers, nozzles and any boilmakers, etc).
Reply:Inconel alloys are primarily Nickel and Chromium, (kinda like stainless steel without the steel) and have good resistance to oxidizing conditions at high temperatures, and also to some other corrosive conditions. Depending on the alloys and the use, welds can have problems with cracking due to segregation at boundaries. Nickel and its alloys are also sensitive to contamination by lead and some other elements which can come from paint or lubricants. If you give more details of your situation, someone here who is more of an expert can probably give a better response.
