Process monitoring in electron beam welding by optimizing the in-process sensor technology by means of backscattered electrons and optical emission

摘要

The demands of the market on manufacturing companies and their products require a time and cost efficient production. There is an ever-increasing need to make welding production more transparent and to ensure and document processes and quality in order to be able to meet the requirements of customers as well as laws and regulations. The extension of sensor technology in electron beam welding can contribute to the achievement of these objectives - by integrating the detection of discrete wavelength ranges of optical process emissions, optimizing the detection of backscattered electrons and correlating the measurement signals to process changes and events, irregularities can be detected in-situ.
