Jasmine M, Austin, Ethan (E-box- specifying welds)

• If you are working with a folded piece of sheet metal, you can add weld corners using the corner feature

• Or, you can use the weldment tool to add welded edges to other joint types or materials

• Welded features show up in the solidworks part model with the accompanying appropriate symbol. In your drawings, you should also specify what type of weld feature you want. There are different symbols used for different types of joints, so check with fabricators to ensure the weld symbol used makes sense in your context!

Abdul H (Base station)
