Hi Ali

The main differences between build-up and buttering is that buttering is used for dissimilar material while build-up is for the same base material

Dear All
what is difference between buttering& build up?because both of them are surfacing activities acc to AWS A.3.0
we have a branch connection in piping that header cut,the hole has a 2in bigger than O.D of branch.
we have a qualified groove wps acc to ASME IX that have a thickness range of 5-30mm.the thickness of header is 25mm.
Now which word must be used in this case?we can build up header with thick of 25mm and width of 45-50mm acc to groove wps?
Regards.
