The automotive industry is going through the most significant development cycle since the start of serial production, or automation of production. In this transition to electrified vehicles, laser processing is becoming more and more important for industrial high-volume production. Trend towards digitization enables laser-based material processing to become more efficient and meet the quality demands set forth by the use of high energy battery technology, as well as in other applications. Sensor systems help to analyze both, the laser equipment as well as the laser process itself. In addition, development of new laser technologies enables new parameters, e.g. green wavelength or extreme short pulses. All of these technologies are relevant for reaching and ensuring high quality production of multiple parts of electrified vehicles, including BIW, drivetrain, batteries and power electronics.

In this presentation we will concentrate on different laser based production technologies and sensor technology and data collection as it relates to quality management of laser welding in eMobility. We will also discuss the relevance of Industry 4.0 solutions in preventing failures and unplanned down time. Advantages of the use of visible wavelength lasers in certain applications will be discussed. This presentation gives an overview about the latest developments, and their relevance for automotive and battery production.
