Prior to forging, it is often necessary to preform billet stock to achieve adequate material distribution. This chapter discusses the equipment used for such operations, including transverse rolling machines, electric upsetters, ring-rolling mills, horizontal presses, and rotary (orbital) and radial forging machines. It describes their basic operating principles as well as advantages and disadvantages.

This chapter provides an introduction to induction soldering. It also illustrates the classification of the different soldering processes according to the heat source, as described in the German standard, Soldering: Categorization of Processes According to Energy Sources, Process Descriptions.

This chapter explains the basic terminology and principles of metallurgy as they apply to extrusion. It begins with an overview of crystal structure in metals and alloys, including crystal defects and orientation. This is followed by sections discussing the development of the continuous cast microstructure of aluminum and copper alloys. The discussion provides information on billet and grain segregation and defects in continuous casting. The chapter then discusses the processes involved in the deformation of pure metals and alloys at room temperature. Next, it describes the characteristics of pure metals and alloys at higher temperatures. The processes involved in extrusion are then covered. The chapter provides details on how the toughness and fracture characteristics of metals and alloys affect the extrusion process. The weld seams in hollow profiles, the production of composite profiles, and the processing of composite materials, as well as the extrusion of metal powders, are discussed. The chapter ends with a discussion on the factors that define the extrudability of metallic materials and how these attributes are characterized.

This chapter contains a list of technical papers and books related to the heat treatment of gears.

Sheet metal spinning is a forming technique that produces axially symmetric hollow bodies with nearly any contour. It is often used in combination with flow forming and shear spinning to manufacture a wide range of complex parts. This chapter describes the operating principles, stress states, and failure modes of each process along with typical applications and tooling requirements.
