The "Create weld between parts" tool is the most frequently applied weld seam type, which does not require specifying the exact weld line location.
When welding parts together the TS automatically creates a new assembly unit and an assembly drawing. Thus, consider the weld as the tool which joins parts (objects) into an assembly.
Before exploring the features of the tool, create a steel plate with dimensions
Copy the plate vertically similarly to the below:
Click on the top plate, and by holding on the “Alt” key pressed,
Move the points selected at 50 mm inwards to the plate.
Proceed likewise for the other faces of the upper plate.
The result should be as presented in the below picture :
Now, let’s make sure that the view settings are configured for displaying
Close the “View settings” window and proceed to welding.
Note that it was of no convention to indicate the weld seam location. The software creates weld according to the weld properties configurations. Open the weld properties window by executing a double-click on the " Weld" tool icon. At the moment, the weld seam is passing around the edge of the part.

.
Depending on the default settings of the " Weld" tool, there are 1 or 2 seam lines displayed in the model. The weld seam is only one but might be specified to be applied from both sides of the part edge: above and below lines. Currently, the below weld line is switched off. In the below picture you can see color framed both weld lines set up fields.
Let’s map the below line seam by indicating an arbitrary weld type and its size value different from zero, for example, 12 mm, to get a clear understanding of the fact that the weld seams can be of various dimensions.
Hiding any welding line is done by indicating the “None” value
Also, the weld seam is not created in case its size value equals zero.
Let’s map out both weld lines of 10mm size.
The “Position” field stands for lining up a weld in the model
As it is of no convention writing in the weld coordinates, thus the very
As you can see from the current example, the weld can subsist only along
Try out toggling between the “Position” field values.
Note there is no option to line up the weld seam bilaterally to the welded
Thus the solution is to create one more welded seam and configure it in
Go to the “Weld properties” menu and setup the welding
seam to the Type 1
, not Type 2
. Select the appropriate weld seam position to get as presented
below.
Create the below line seam with the size value of 10 mm.
It is also possible to model various weld seam shapes, such as intermittent
The intermittence of the seam lines is to be set up separately, same as
Set up the seams intermittence configurations as is shown below.
Deleting the top plate automatically deletes the welds.
None of the welds can exist without the welded parts to which it refers.
Now we are assured that the welded seams have been deleted along with
Let’s examine creating a butt type of weld. Copy the plate horizontally
Enable the “Create weld between parts” tool and weld up the
Switch the weld type from “Around”
to the “Edge” type
.
Now the weld seam has the triangle shape, though it is not viable in real
practice. Switch the weld type to the
option. The current weld type requires setting up the bevel
angle value. Let’s set its value at 45 degrees.
As you can see in the above picture, the weld seam has changed its type to the butt. Now before getting welded, parts shall get a prepared chamfer edge.
Also, it is important to leave an opening between the parts, thus
Let’s proceed by indicating the root opening value of 2mm.
Also, make sure you indicate the root opening value for both: above and
Let’s create the root face as well, where the plate thicknesses are 20mm, with 18 mm included as beveling thus the value to be written is 2 mm.
The "Preparation" field takes off the part’s body the welded seam volume by applying the added material substance. If the field value equals “None” then welding is reflected within the part body but does not subtract its volume or affect its geometry.
If the field value equals “Auto” then the geometry of the joinable parts will be subtracted by the welding seam bodies. The welding seams representation mode will also get modified, as the welds get their own space and transform into the only chamfer present at the drawing.
Thus it is possible to configure any edge of a part.
Let’s explore the case study where parts are joined to the profile

Configure the properties of the beam according to the above table.
Create a plate at the side of the beam as it is shown below, indicating
Click at the plate, and by holding on the “Alt” key pressed, select the points adjacent to the beam wall. Press the “Shift” key, and by a double click at a point, go to the “Chamfer properties” window.
Set up the angle value of 45 degrees, and the axial dimensions as 20 x
Move the plate to the beam center point by deploying the Ctrl+M hot key
Now let’s evaluate the notion of “assembly”, which is defined as a group of parts joined into an integral unit (assembly). In this case, welding is done by the manufacturer at the plant.
When creating welds it is of high importance to firstly select the beam, thus the assembly title will coincide with its name, but the beam will become the main component of the assembly.
Further on, when welding up parts in the TS first object to be selected
The location of the welded seams is of no particular importance, as the
To select an assembly it is sufficient to make a click at any of its objects
Let’s adjust the welding seam: switch it’s type from the “Around”
to the “Edge”
and set up the weld size at 6 mm bilaterally, Fillet type

.
Toggle between the position options until the weld seam gets aligned as shown in the picture below, thus connecting the bottom plate line to the beam .
The position field coordinates may vary depending on the beam drawing
The single weld is not enough for joining the plate to the beam, though
Create one more weld seam to be aligned along the beam wall similar to the below picture. The new weld seam’s configurations are the same as the previous ones, except for the position parameter value.
By analogy create the 3rd weld seam and configure it to the position type
Make sure you indicate the beam as the main part of the assembly.
Thus the plate is completely welded to the beam.
One of the most important welded seam properties is that it can not exist
Deleting the plate automatically deletes the welds, which are not just
The beam got cleared up off the welds. Restore the welded plate by enabling
Try out executing "Copy Special-Mirror" of the plate to the other side of the beam. For this, press the Ctrl+P hotkey combination to go to the view plane.
Make sure that the Z-axis is perpendicular to the eye gaze direction,
Select the plate, and in the right-click menu, proceed to the “Copy
Another important property of the welds is that they are copied along with the welded parts to which they refer, even though welds have not been selected. Also, note that this condition plays out only in case there is available appropriate geometry. For example, copying the plate to a blank space will not duplicate the weld seams, as there is no connectable object to the plate.
In the below picture you can see that the duplicated plate got adjusted
Check this out by holding on to the Alt key pressed and clicking at the
As you can see all the objects were selected, even though initially we
Let’s explore the "Workshop
/ Site" attribute
.
This parameter stands for defining whether the parts will get included
in the assembly (into a common drawing). Indicating the “Workshop”
weld type contributes to welding the parts at the plant, thus they are
to be included in a common assembly drawing. Select all the weld seams
of the plate and switch the weld type to the “Site” class
.
Repeatedly select the assembly by applying the "Alt" key.
To assure better visibility go to the Ctrl+5 display mode.
From now on, the parts are available on the weld seams but still are not
There is a separate tool for selecting an assembly as an object type, not a kit of objects. This tool allows editing assembly properties as well as selecting it without holding on any key pressed.
Note that the selected objects have a different visual display: the assembly object is framed with block faces, outlining its dimensions, and the main assembly part gets rendered in orange color when selecting the assembly by the right-click menu “Inquire” tab.
The “Inquire object” tab runs the assembly text report. We will examine in detail the issue of creating and editing such reports in the following chapters. Double-click at the main assembly object (orange colored) runs the assembly properties menu which is completely different from the assembly report.
At the moment, let’s make it a rule, not to bring any changes to

In the “Inquire object” report there is available all essential
At the moment, let’s, first of all, get the assembly name -Peter-0(?), where the question mark stands for notifying that the assembly number had not been assigned yet, as numbering was not carried out yet. The numbering topic will be examined in the creating drawings case study.
Let’s examine one more welding component type, such as the endplate. Create an endplate with its points located at the I-beam edges. Set up its width parameter at 18 mm.
Weld up the endplate to the I-beam. It is important to indicate the beam as the first assembly component with the purpose that the assembly gains the prefix numbering of the main component.
Locate the weld seam above the I-beam.
It is obvious that the weld seam can not be created as it is shown in the above picture. Welding up the parts with no edge preparation fails at realizing a full penetration weld, which comes evident after executing the parts surface treatment.
Thus when welding up the endplate definite measures are to be taken to assure full penetration. There are the following alternate solutions to this matter:
|
Increasing edge plate’s dimensions |
Reducing edge plate’s dimensions |
Executing the edge preparation at plate |
Executing the edge preparation at beam |

Let’s copy the beam with the edge plate 3 more times and implement
Type 1- Increasing the dimensions of the edge plate.
Let’s try out the first solution which implies increasing the plate’s
Similarly to the above proceed for the bottom points of the plate, by
Make sure that welds are set out visible at the "Exact" representation mode at the “Display” menu of the "View settings". At the "Welds settings" menu configure the welding seam to be bilateral, and of the size equal to 14 mm. It is important to mention that the welding seam size is determined by calculation.
The size value of 14 mm is an arbitrary rate, thus do not percept the

Let’s create the part’s default views and get to the part’s "Side view". Adjust the weld seam in the way to get grooved into the part.
Switch the weld type to the "Bevel groove bevel butt" option.
Specifically for this welding type, it is compulsory to
indicate the welding chord and the angle parameter values, otherwise the
weld seam is not created. Set out the “Preparation” field as
“Auto”.
Refer to the below to align the weld seam correctly.
Create all the weld seams required. Note that the seams along the I-beam

Type 4 тип - Executing the edge preparation of the beam
Set out the edge preparation parameters similar to the previous case study, except for indicating the “Placement” field value as “Main part”. In the current case study, the beam is the main assembly component, thus the edge preparation is to be applied to it, according to the “Placement” parameter.
Compare your results to the below:
Add up the rest seams.
Keep in mind that the seams along the I-beam wall shall not have
