The previous two chapters have introduced a number of manufacturing techniques for producing single components. Wherever possible, it makes sense to reduce the number of components needed in a product as this simplifies both the manufacturing control and assembly processes. However, the vast majority of engineering products require a number of components and therefore need a manufacturing technique to create the assembly. The technique chosen will depend on a variety of factors, such as the permanency of the joint, the materials used, or the ability of the assembly to withstand a heat input. Figure 9.1 summarises the main techniques available. In this chapter we will discuss the techniques and later, in Chapter 13, we will expand upon the reasons for selecting a particular method.
