Note: AWS D1.1 Table 3.4 prequalified groove details. Standard bevel angles: 30, 37.5, or 45 degrees. Root face typically 0-1/8 in.

Reference

AWS D1.1: Standard V-groove = 60 deg included (2 x 30 deg bevel) or 75 deg included (2 x 37.5 deg bevel) Bevel depth = plate thickness - root face Groove width = 2 x tan(bevel angle) x bevel depth + root opening Effective throat = plate thickness for CJP groove welds
