Bevel

A bevel defines the edge preparation applied to plates for welding. It is part of the overall edge preparation, which includes both the bevel geometry and a chamfer. The bevel geometry is defined by key parameters such as:

• Opening angles α on the positive side and β on the negative side,

• Gap, which defines the distance between prepared edges to be filled during welding,

• Nose or knee to define the root geometry,

• Radius for while U-shaped bevels to describe curved sections. Other bevel shapes consist of straight-line segments.

Bevels follow standardized bevel types that define the basic geometric shape. For more information, see Bevel Types. To use bevels in a project you can define bevel codes. For more information, see Bevel Codes.

Bevel definitions also account for real manufacturing conditions. When plates of different thicknesses are joined, variants of the base geometry may be required. For more information, see Bevel Variants.

Each bevel has an orientation relative to the plate surfaces. The positive (upper) side and negative (lower) side determine how parameters such as angles are applied and how the bevel is represented. Depending on the drawing or manufacturing context, the bevel can appear as a normal or reflected representation.

Overall, the bevel concept combines standardized bevel types, project-specific definitions (bevel codes), and parameter-driven variations (variants). This approach enables consistent and adaptable edge preparation for welding.
