With increasing demands on electrical-mechanical connections with regard to temperature resistance and conductivity, the joining process of laser beam spot welding is becoming increasingly important for the micro range. This book presents selected methods for process control based on experimental investigations, divided into algorithms that can be carried out with or without process knowledge. In addition, the sensors required to set up such a control system are discussed in detail. On the basis of a joint connection produced industrially in series, the detectability of certain welding defects as well as their connection with the system technology are demonstrated by means of a statistical evaluation of recorded process signals.
