Ⅰ. Overview
Compound Bevel is an efficient solution to complex welding requirements.
When no weld seam is reserved in the part design, you can use the Compound Bevel feature in TubesT to modify the design and create a weld seam.
Difference between Add Bevel and Compound Bevel
-
-
- Add Bevel: Adds a bevel based on a zero-degree base. The resulting bevel angle is the angle you specify and is independent of any bevel already defined in the original drawing.
- Compound Bevel: Adds an additional bevel angle based on the bevel angle already recognized from the original drawing.
-
This tutorial describes Compound Bevel. For details about Add Bevel, see Add Bevel.
Ⅱ. Version and Permissions
1.Version
In 2025V2.2 and 2025V3, compound bevel parameters are configured under Compound Bevel, where the bevel generation method can be set through Describe the superposition process.
The following changes were introduced in 2026V1 and later:
-
-
- The former Describe the superposition process has been extracted into the dedicated Compound Bevel feature. Add Bevel now only supports Describe final shape.
- The main toolbar icon has been changed from Add Bevel to Compound Bevel.
- Bevel Type has been renamed to Welding Filling Position.
-
To use these features, make sure your software version supports them. If you are using an earlier version, upgrade your nesting software first.
2.Permissions
The feature is available in TubesT Steel Structure Version, Professional Version, TubesT-H and Small Tube Professional Version. It is not supported in TubesT Lite, TubesT Small Tube, or 2-Chuck Version.
Before using this feature, click the gear icon in the upper-left corner of the software, then go to User Settings → Machine Config and enable A axis bevel cutter. The A-axis swing limit should be configured according to your machine specifications. A typical value is 45°.
Ⅲ. How to Use
1. Overall Workflow
It is recommended to configure Compound Bevel after importing the part and before adding techniques.
2. Steps
Click Compound Bevel on the top toolbar. Select the Welding Filling Position and set the compound bevel parameters according to the welding requirements.
Then, select the scope to which the settings apply and click OK to apply them.
3. Parameter Description
| Parameter | Description |
|---|---|
| Welding Filling Position |
Depending on whether the weld is filled from the outside or inside and whether a root is reserved, Welding Filling Position is available in the following three types. More types will be added in future versions to support scenarios such as double-sided weld filling with or without a root.
|
| Bevel angle |
As shown below, angle A of the compound bevel is the Bevel Angle.
|
| Root length |
A root face is retained at the bevel root to prevent burn-through. The length of the root face is the Root length.
|
|
Angle datum |
Section vector: The normal vector before bevel recognition is used as the zero-degree base vector. This results in approximately the same A-axis angle.
|
|
Bevel vector: The normal vector after bevel recognition is used as the zero-degree reference vector, resulting in a more uniform weld seam.
|
|
| Apply to |
When Current View is selected, you can apply the settings to the selected toolpaths or to all toolpaths in the current part displayed in the software interface.
|
|
When Part list is selected, you can choose specific parts or all parts from the part list on the left side of the software.
|
|
|
Select Path Apply Range |
To meet different machining requirements, you can filter the target toolpaths by the following criteria:
These filter conditions can be used individually or in combination, allowing the settings to take effect on all toolpaths simultaneously.
