Disadvantages similar to the ones mentioned in the first method exist however, you can modify assembly constraints to create variants of weldment assemblies with this approach. Optionally, you can derive the part file into another part file to show machining on welded assemblies. With this approach, you can derive the weldment assembly (.iam) into a single-part file (.ipt) and model the welds in the derived assembly file using part features. (However, in drawings, you will not be able to create the different stages of weldment design.) Figure 10.1 shows this methodology.
You could place the part weldment into an assembly and then create presentations and drawings of that assembly. Besides, the assumption is that the designer does not need to create the different stages in design documentation from a single weldment assembly. Still, this might be an acceptable strategy for small weldment designs that have minor design changes over a period of time. In addition, the bill of materials (BOM) will not list all the individual components needed to assemble the welded structures. You will not be able to see certain edges separating weld beads and components in drawings because they will not even exist (they will be merged out) in the part design. The main difficulty is creating drawings with different stages-for example, as-assembled, as-welded, and so on-from a single design. However, this will be one big mess of a design that has no logical partitions. With this approach, you use the rich modeling features of the part (sweeps, chamfers, fillets, and lofts) to create a wide variety of weld bead shapes. You can create a weldment design using part features in part files.
Therefore, this chapter is not applicable if you have only the Autodesk ® Inventor LT ™ program installed. Most of the topics in this chapter involve working with assembly files.
Weldments are available in the assembly environment as a subtype of the assembly document. You will also learn some tips and tricks along the way.

Starting from weldment workflows and design methodologies, you'll look at preparations, weld beads, machining features, and weld symbols, as well as how to document the weldment design. You will explore the various aspects of weldment design. Weldment Designįor this chapter, you must have a good understanding of parts, assemblies, and drawings.
