The appropriate tolerances for the welded cross-section are specified in AWS D1.1-2004 Section 5.23. However, at bolted splices for such members, AWS D1.1-2004 Section 5.23 is silent on this subject. AISC recommends that the permissible deviations for girder depth in AWS D1.1-2004 Section 5.23.9 be applied to depth at bolted splices. Any differences within the prescribed tolerances at such joints should be taken up, if necessary, by shimming.
