where in b31.1 does it tell us how wide you can weave to be acceptable

It doesn't.

Bead width limitations are addressed in few codes for piping or at least B31.1 and B31..3

Often the individual WPS (Welding Procedure Specification) will address bead width when heat input limitations are required. B31.1 and B31.3 do not address width at all that I can recall. ASME Sec I and Sec VIII may for repair welds or welds ommiting PWHT (Half Bead Temper Technique).

Heat input can be controlled somewhat with bead width but a more accurate method would be travel speed.

Have a nice Day

Gerald,

Please refresh an old man's memory where bead width is addressed in B31.1 and B31.3.

Thank you,
QCRobert

Robert,

I should probably wait and let Gerald reply for himself, but I think if you look closely at the wording he is actually saying that those codes 'do not' deal with bead width.  Hope I am reading him correctly.  And that "few" codes do address bead width. 

Have a Great Day,  Brent

Your correct. Poor wording. 31.1 and 31.3 were the only ones I was sure of. Can't speak on any others.

Sorry for the confusion.

Oscillation (or weave bead) is only an essential variable (as per ASME IX) for specific automatic or machine welding processes.
Non essential variable for manual or semi-automatic welding processes,
