Buttering is a technique in which weld is applied to the surface in order to acheive desired properties or required dimensions.
For example in fit-up/butt joint, if distance between two butting members is excess, buttering is done on one member to reduce the gap.
Buttering is also done on surfaces to provide metallurgically compatible weld metal for subsequent completion of weld.

Dear Sir
Can anyone describe me what is "BUTTERING" stands
for in welding joint. If it is done before depositing the weld metal on job, is
it necessary to remove the same by back chipping.

Dear All
I have the following queries regarding Buttering:
1) Can we use buttering during pipe joint bevel preparation?
2) Whether there will be any chance of crack formation due to this?
3) Is there any code reference for the same?
Regards
