Weld bead features in Autodesk Inventor include a cosmetic weld, a solid fillet weld, and a solid groove weld. All weld bead types reside only in the Welds feature group. Each is represented with a unique icon in the browser.
Welds capture the weld specification, associate it with selected geometry, and display a weld symbol. Cosmetic and solid welding symbols can be recovered and created automatically in drawing views. You can also automatically generate caterpillar annotations for solid body fillet welds.
You can create a welding symbol simultaneously with the weld bead or you can create it in a separate operation.
How are cosmetic welds and solid welds different?
Cosmetic welds are created as graphical elements. These graphical elements change the appearance of model edges to indicate they were welded. Cosmetic welds also create a standard weld symbol containing a full description of the weld feature. It does not create the actual weld bead geometry, and when calculated for mass properties, contributes an approximate mass. Because of these characteristics, cosmetic welds can easily represent a wide range of weld types.

Solid welds use the weld specification to create a 3D representation of the weld bead and a weld symbol on the assembly weldment. The solid weld bead adds material to the model that contributes to the mass property calculations. Use solid welds for design cases where interference checking or the effects of welds on mass properties are a concern.

Different weld types and values can be defined for both the arrow side and other side of a cosmetic weld. Arrow side and other side definitions for a solid weld can only differ in value.
How is the workflow different for cosmetic welds and solid welds?
Complete control of weld specification capabilities is available for all weld feature types. The main difference is that you select edges to create a cosmetic weld, and faces to create a solid weld.
Weld preparations are optional for solid welds, but are not required for cosmetic welds. The cosmetic weld symbol contains the description of weld preparations required for the selected edges.
Create weld bead features in weldments
In a weldment assembly, use commands on the Weld tab to create fillet welds, groove welds, and cosmetic welds. Create intermittent or continuous fillet welds along the length of selected faces or use a groove weld to connect two faces with a solid weld bead.
The following images show cosmetic, fillet, and intermittent fillet welds.



Weld bead features are always affected by post-weld machining features, but are not affected by weld preparation features. Weld bead features are also not included in assembly feature participation lists.
You can create a welding symbol when you create a weld bead or you can create it in a separate operation.
Fillet welds build up corners by adding material between one or more faces of a single part or multiple parts.

For more information about the meaning of values in the welding symbol, see the Model welding symbol reference.
Select Full Face Weld and Ignore Internal Loops check boxes to specify the treatment for the second selection set.

For more information about the meaning of values in the welding symbol, see the Model welding symbol reference.

Create a cosmetic weld feature
If you prefer, you can create the weld symbol later. The cosmetic weld bead is nested below the weld symbol in the browser Weld folder.
Add end fills to beads in weldments
To remove an end fill, click End Fill and then click the face again to turn off the face highlight.
Export weld bead properties to spreadsheets
To help you determine accurate weld rod usage, fabrication time, and bead weights, you can export weld bead physical properties to a spreadsheet. You can query the mass, volume, length, type, and name of individual beads in the weldment assembly. Or you can list all the weld beads in the current assembly and in all referenced weldment files. The names of the referenced files are included in the report. You can generate a weld bead report from any assembly document.
Length and Area values are not reported for groove welds.
Once the weld bead properties are exported to the spreadsheet, you can insert your own formulas to obtain cost information or paste the table into a drawing for reference.
Set visibility of weld bead features and symbols
Weld bead features and symbols are on by default when they are first created. They remain on until you change their visibility. When a weldment is placed in another assembly, its weld bead features and symbols are visible in the assembly.
You can control the visibility of weld bead features and symbols for an entire weldment, for the Welds feature group, and for individual weld bead features.
You can turn off both the symbol and the weld bead feature or just the symbol. Turning off weld bead feature visibility automatically turns off the associated weld symbol as well.
Weld bead feature and symbol visibility are reflected in design view representations.
To set visibility for the Welds feature group
You can change visibility for all assembly weld bead features or weld symbols in the Welds feature group using an option on the context menu.
To set visibility for selected weld bead features
At the feature level, you can set visibility for symbols only. Weld bead feature visibility is not available.
To set visibility for an entire weldment or assembly with subweldments
You can delete individual features from any of the three weld feature groups . You cannot delete the actual weld feature groups.
When you delete a weld bead feature , its associated welding symbol is also deleted. The weld bead feature annotations and any drawing welding symbols associated with the weld bead feature will be deleted the next time the drawing updates.
When you delete assembly features from a weld feature group, you might need to reapply constraints or recreate features.
Creates a fillet weld feature in a weldment assembly. A welding symbol may be created simultaneously with the feature or it may be created in a separate operation.
The weld bead and the welding symbol are separate features in the welds folder of the browser. The welding symbol can be associated with the fillet bead feature so that changes to the fillet bead update the welding symbol values. Changes to the welding symbol cannot update the fillet bead feature. When consumed by a welding symbol, the fillet weld is a child node of the welding symbol.
The Bead box specifies the parameters for constructing the fillet weld. | ||
Selection and Size | Selects the faces to define the fillet weld. Select the Chain check box to select tangent contiguous faces automatically. | |
| | Leg Length constructs a fillet weld based on leg length (height and width). If only one value is entered, leg lengths are equal. | |
| | Throat constructs a fillet weld based on the distance between the weld root and the face of the fillet weld. | |
| | Direction changes the start position of an offset weld. | |
Contour | | Specifies Flat, Convex, or Concave weld bead process shape and if appropriate, an offset distance. Offset is used with Concave or Convex contours to control the inward or outward bow of the weld bead face. |
Intermittency | | Specifies intermittency of a fillet weld bead, specific to the active standard. ANSI standard specifies bead length and the distance between bead centers. ISO, BSI, DIN, and GB standards specify bead length, spacing between beads, and the number of beads. JIS standard specifies bead length, the distance between bead centers and the number of beads. |
Extents | Determines the method for starting and ending a fillet weld. A fillet weld can terminate on a work plane, on a planar face, or extend across all selected geometry for a full-length weld. The start and end position of a fillet weld can also be offset from a model edge. Click the arrow to select the extent method.

Creates a groove weld feature in a weldment assembly that connects two face sets with a solid weld bead. A welding symbol can be created simultaneously with the feature or it can be created in a separate operation.
The weld bead and welding symbol are separate features in the welds folder of the browser. There is no association between the welding symbol and the weld bead feature so you can specify any welding symbol values for the weld bead feature. When consumed by a welding symbol, the groove weld is a child node of the welding symbol.
The Bead box specifies the parameters for constructing the groove weld. | ||
Face Sets 1 and 2 | Selects the two sets of faces to connect by a groove weld bead. Each face set must consist of one or more contiguous part faces. Full Face Weld specifies how the weld bead appears for both face sets. | |
| | Clear the check box to specify that the weld bead ends at the extents of the smaller face set. | |
| | Select the check box to specify that the weld bead extends to consume both face sets. If face sets 1 and 2 are different lengths, the weld bead expands to fit both faces. | |
Chain Faces selects multiple tangent faces. | ||
Ignore Internal Loops determines if a selected face set results in a hollow groove weld or a solid weld. | ||
![]() | Clear the check box to specify that the weld bead extends along the loop, but not the face. | |
![]() | Select the check box to specify that the weld bead spans the internal loop to cover the entire face. | |
Fill Direction | Sets the direction in which groove weld face sets are projected onto one another when connected by the groove weld bead. To define the fill direction, you can select:
| |
| | | Projects the weld bead at the angle of the first selected face set. |
| | | Projects the weld bead perpendicular to the second selected face set. |
| | Radial fill | Projects the weld bead around a curve. Fill Direction is not available when the Radial Fill check box is selected.

Creates a cosmetic weld feature in a weldment assembly. A welding symbol may be created simultaneously with the feature, but may be created in a separate operation.
The weld bead and the welding symbol are separate features in the welds folder of the browser. The welding symbol and the weld bead feature are not associated, so you can specify any welding symbol values for any weld bead feature. When consumed by a welding symbol, the cosmetic bead is a child node of the welding symbol.
Cosmetic weld beads are useful when the design does not require interference analysis or the aesthetic appearance of solid weld beads. Their approximate physical properties can be included in mass properties.
The Bead box specifies the parameters for constructing the cosmetic bead. | |
Select Mode | Sets the selection preference for areas on which to apply the cosmetic weld bead. Edge is the default. Chain automatically selects tangent, contiguous edges. Loop selects a closed loop. |
Extents | Determines the method for ending a cosmetic weld. A cosmetic weld can terminate on a work plane or extend across all selected geometry for a full-length weld. Click the arrow to select the extent method. All creates the weld on all features and sketches in the specified direction. From-To select beginning and ending faces or planes on which to terminate the weld feature. In a weldment, the faces or planes may be on other parts, but must be parallel. |
Area | Sets the cross-sectional area for a cosmetic weld bead so the physical properties of the cosmetic bead can be calculated. |
