Re: [MW:5566] Buttering of weld joints

Well Das,            The buttering is actually the edition of material by welding on the faces of the joint to provide final shape or suitable transition to the joint. For example: when we have to get an opening on the vessel for the nozzle during fabrication of vessel, and the size of the opening is found bigger than the required size by mistake after cutting. then we have to do some weld build up on the face of the opening to get the required size, this weld build up is called Buttering. See the definitions in the ASME sec IX may it will help you. Regards, M.

If it is done before depositing the weld metal on job, is it necessary to remove the same by back chipping.   -- To post to this group, send email to materials-welding@googlegroups.com To unsubscribe from this group, send email to materials-welding-unsubscribe@googlegroups.com For more options, visit this group's bolg at http://materials-welding.blogspot.com/ The views expressed/exchnaged in this group are members personel views and meant for educational purposes only, Users must take their own decisions w.r.t. applicable code/standard/contract documents.
