Tutorial for Solidworks Weldments

This feature inside Solidworks allows the designer to create welds between jointed parts and model the Weldment structure as a single entity.

I will do a simple stool to demonstrate this functionality inside Solidworks.

The part above was created using angle iron structural members present in the Weldments tab. Prior to defining the structural member that you will use you need to first create a sketch of the outline.

Upon creating the sketch you can then define the specifications of your structural member. You can either choose from:-

  • Angle iron
  • Square tube
  • Pipe
  • c channel
  • Rectangular tube
  • S section

You can then create the sketch for the stool legs

I then created the reinforcements for the legs and added gussets to stabilize the structure. I used the mirror bodies’ tool to quickly reproduce my results for the other three corners of the structure.

You can then proceed to define the weld beads. We do this by first defining the weld path then specifying the weld parameters.

Once you have done the weld path you can click on the green marker to process the weld beads. The beads are however not visible and have to be turned on at the view tab.

To test our structure for soundness we can proceed to run a structural analysis on the model.
For a static study we need to define the fixed sections and also define the loads and their point of application.

We can then proceed to define our load which will be applied at the top of the structure.

We can then proceed to create the mesh and run the analysis.

Once you run the static analysis you and then generate the report, animate the analysis and see all possible points of failure. You can then redesign you structural member based on the cause of failure.
