How do you create a welded assembly in SolidWorks?

Creating a welded assembly in SolidWorks is best accomplished by utilizing the weldments feature, which is specifically designed for defining structural members and joints. This feature allows you to create and manage weldments effectively by providing tools to specify the profile of structural components and their connection details.

When you use the weldments feature, you can define different types of joints, such as fillet welds or groove welds, and specify the conditions under which they are applied. This not only enhances the accuracy of your welding representations but also streamlines the process of creating complex assemblies made from multiple structural members.

The other methods mentioned do not specifically cater to the creation of welded assemblies. While combining parts in an assembly is a fundamental aspect of SolidWorks, it does not incorporate the specific parameters and configurations that are unique to welding. Similarly, grouping parts through the assembly tree and using the extrude tool do not provide the necessary detail and function tailored for weldments, making the weldments feature the ideal choice for creating welded assemblies.
