What is a typical bevel angle for preparing a groove weld on carbon steel plates?

• A. About 60 degrees total included angle (approximately 30-45 degrees per side).
• B. 60 degrees per side.
• C. 0 degree flat.
• D. About 60 degrees total included angle (approximately 60-70 degrees per side).

Answer: (D)

When preparing a groove weld on carbon steel, the goal is to form a groove that allows full penetration and proper filler metal coverage. A common, practical target for the groove geometry is a total included angle of about 60 degrees. That usually means roughly 30 degrees of bevel on each side, though the exact per-side angle can vary a bit with plate thickness and the welding process. A flat, 0-degree joint would not provide a groove to fill, so it’s not typical for a groove weld. Bevels that are much steeper per side would create a much wider, shallower groove and aren’t standard for this Joint geometry. So the gist to remember is: aim for about a 60-degree total included angle, which yields a workable groove for effective welding.
