What types of design features favor manufacture as a joined assembly?

To determine

The types of design features that favor manufacture as a joined assembly.

Explanation of Solution

The manufacture of joined assemblies of two or more components is favored when the product is required to be large, composed of multiple parts with different prosperities, or has an unusual complex shape. The components of the joined assembly are smaller and easier to handle, simpler shapes are more comfortable to manufacture, or segments are made from different materials.

When welded structures are subsequently machined, the material removal frequently unbalances the residual stress equilibrium, and the material distorts to achieve a new balance of forces. In essence, it distorts during machining. Weldment that are to undergo appreciable machining should be given a stress-relief heat treatment prior to the machining operation.
