Acoustic process monitoring in laser beam welding
Procedia CIRP, 2020 Abstract Structure-borne acoustic emission (AE) measurement shows major advantages regarding quality assurance and process control in industrial applications. In this paper, laser beam welding of steel and aluminum was carried out under varying process parameters (welding speed, focal position) in order to provide data by means of structure-borne AE ...

Physics Procedia, 2014 AbstractUp to date the evaporation process in laser beam welding of alloys with volatile elements is not completely understood. This paper discusses the phenomena occurring at the welding process of brass with 37m% zinc. Since copper has a solidification temperature of 1,087°C and zinc vaporizes at a temperature of 907°C, a strong evaporation takes ...
