The BOM outlines the different part components. The main advantage is that the weldment can be documented as-assembled, as-welded, and so on. With this approach, you use a mixture of cosmetic, fillet, and groove welds with preparations, machining features, and weld symbols at the assembly level. Figure 10.2 shows the document layout of this methodology.Р”Р‡igure 10.2 Weldment assembly and derived technology

This might be a good strategy for weldments where a BOM listing is required and there is no need to document different stages of weldment design from a single weldment assembly. The preparations, welds, and machining features will all exist in the derived component files. 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.

Weldment assembly and derived technology.

Once the weldment design is done, it helps to document the various stages of weldment design in the drawing.Р”Вepending on the need for documentation, interference analysis, mass properties, and other design criteria, you can group the weldment design methodologies into the following four broad categories, which are defined in more detail in this section: This view includes features that might penetrate or cut through weld beads.Р”Р„ll these represent the various stages in weldment design. As-machined A view of the final welded assembly with the machining features created after the welding had been done. As-welded A view of the assembly with weld preparations and weld beads but no machining features.Р”Р€. As-assembled A view of the assembly with no weld preparations, beads, or machining features.Р”Сћ. You will start by defining the different design methodologies:Р”РЋ. The design methodology you use depends on your individual needs and requirements. Unfortunately, there is no РІР‚Сљone-size-fits-allРІР‚Сњ strategy. One of the basic questions in weldment design is what design methodology should be used to create weldments.

Generate and maintain a consistent BOM across welded assemblies, drawings, and presentations.

Create and edit different kinds of weld beads, such as cosmetic, fillet, and groove.

Create and edit weld preparations and machining features.

Select and use the right weldment design methodology.

Therefore, this chapter is not applicable if you have only the Autodesk Р’В® Inventor LT РІвЂћСћ 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.
