Note: U-groove is the most economical groove prep for plates over 3/4 in. Requires machining but dramatically reduces weld metal and distortion. Typical bevel angle 0-20 deg per side.

Reference

U-Groove Volume Calculation: Semi-circular root area = 0.5 * pi * r^2 Taper area = 0.5 * (bottom width + top width) * straight depth Bottom width = 2 * root radius Top width = 2r + 2 * tan(bevel angle) * straight depth U-groove saves 40-60% weld metal vs V-groove on thick plate
