Cladding or Weld Overlay for Tubesheets

[ashaykadam]

In what conditions Cladding is preffered on Weld Overlay for Tubesheets?

One reason may be compatibility of materials w.r.t. welding.
Eg., as Titanium is not weldable with Non-Titanium materials, the tubesheet is required to be cladded.

Are there any other factors which decides when to go for Cladded Tubesheets than Weld Overialed one?

Thanks.
