Buttering According to AWS D1.1

[BJAguila]

I want to qualify a buttering procedure accd. to AWS D1.1, what will be the groove preparation, range qualified for this procedure and also the test required when qualifying a buttering procedure.

Is this a repair procedure or a just an overlay with repeated stringer passes? Most cases I have seen buttering is just part of another pre-qualified welding procedure.

Buttering is generally used for corrections of weld gaps. This would be done to the qualified procedure for that joint.

If you have been asked to qualify a buttering procedure by your client, just qualify as per the joint that will be welded and just add additional hardness across the buttering into the HAZ and the parent.
