Note: J-groove prep requires machining but saves significant weld metal on thick plate. Typical root radius 3/8 in. AWS D1.1 prequalified J-groove: 20 deg bevel angle.

Reference

J-Groove Volume Calculation: Curved portion area = 0.25 * pi * r^2 Straight bevel area = 0.5 * (bottom width + top width) * straight depth Total = curved + straight + 10% reinforcement J-groove saves 30-50% weld metal vs equivalent V-groove
