Weld Bead vs Fillet Bead: SOLIDWORKS Feature Comparison

Article by Brad Hakeman on Sep 09, 2022

You might ask yourself why there are two Bead features in SOLIDWORKS Weldments; Weld Bead and Fillet Bead. In this quick tip, we compare the two to help you better decide when to use one over the other. 

SOLIDWORKS Weld Bead Feature

In a previous article, we discussed adding a Weld Bead Feature to your SOLIDWORKS Weldment Part file. Refer to the following article to learn how to add Weld Beads to your Weldment Part file: Creating and Adding Weld Beads in SOLIDWORKS Models & Drawings.

Benefits of the Weld Bead

In SOLIDWORKS, the Weld Bead’s major advantage over the Fillet Bead is performance. The Weld Bead feature defines your welds but does not generate any solid bodies. The Weld Bead is a graphical body (think “Cosmetic Threads” for Weldments) that won’t require extra resources from your PC, allowing for a smoother modeling experience.

Although the Weld Bead Feature creates a graphical body, a Weld Bead Folder is populated in your FeatureManager Design Tree. Weld Bead Properties contain such details as Weld Material, Weld Process, Weld Length, etc. (Figure 1) and can be shown in your SOLIDWORKS Drawing in a Weld Table (Figure 2).

SOLIDWORKS Fillet Bead Feature

The Fillet Bead feature does not generate Custom Properties that could be located in a weld table. The Fillet Bead Feature generates a solid body found in your SOLIDWORKS Weldment Multibody part file. (Figures 3 & 4)  

By using the Fillet Bead option to define your welds, the SOLIDWORKS Weldment file can now be accurately used to run Interference Detection in a tight corner to verify whether your weld bead might cause issues later in your Assembly if another component is mounted in close proximity to the weld.

How to Add a Fillet Bead in SOLIDWORKS

To add a Fillet Bead to your Weldment, go to Insert > Weldments > Fillet Bead. (Figure 5)

With the Fillet Bead feature open, select the type of weld from the drop-down (Full Length, Intermittent, or Staggered). (Figure 6)

Select the faces of the two bodies to be welded and set the fillet size and/or pitch options. (Figure 7)

Since the Fillet Bead feature generates a solid body, it will aid in calculating accurate Mass Property results. 

Additionally, because the Fillet Bead generates a physical representation in your SOLIDWORKS Part file, drawing views will automatically include the Fillet Bead. (Figures 8 &9)

The choice is yours to make. As with any tool in SOLIDWORKS, the decision on which feature to use is up to the end user. The choice comes down to how you intend to use the weld information.  

If you’re creating a detailed Weldment Drawing, including weld properties and callouts, the Weld Bead feature would be preferred while minimizing the impact on performance.  

However, if the physical weld bead is required for inspection or mass property calculation, the Fillet Bead is the feature to select.
