What is the bevel angle range on pipe?

• A. 25-35 degrees
• B. 30-37.5 degrees
• C. 40-50 degrees
• D. 10-20 degrees

Answer: (B)

Bevel angle refers to how much the ends of the pipe are cut to form the groove for a butt weld. For typical pipe welding, each pipe end is beveled to about 30 to 37.5 degrees. This range creates a V-groove with an included angle of roughly 60 to 75 degrees, which gives enough width for proper root penetration while keeping heat input and distortion reasonable. If the bevel is shallower than about 30 degrees, the groove becomes too narrow and may hinder fusion or require extra filler. If it’s steeper than about 37.5 degrees, the groove becomes very wide, increasing weld size, heat, and potential distortion. So the standard, practical range to use is about 30–37.5 degrees.
