Abstract

Sustainability is a relevant objective for the manufacturing industry, which means to produce goods and services in a way that is cost-effective and preserves the environment. Therefore, it is important to analyze the energy consumption of manufacturing processes and equipment. The objective of this chapter is to provide an approach for the analyses of sustainability and energy efficiency of joining processes and facilities. First of all, the concept of sustainability is explained in general and illustrated by using key performance indicators. Then, data sources are described that may be used for sustainability and energy efficiency analyses. In addition, approaches to influence the sustainability of joining equipment, joining processes, and joining facilities are discussed. The energy consumption of joining equipment is composed of base, idle, and joining energy. The parameters that influence the joining energy depend on the type of joining process. This is discussed in detail for fusion arc welding, oxy-acetylene gas welding, torch brazing, mechanical fastening, and adhesive bonding. The section on joining facilities emphasizes the indirect ...
