Laser joining processes, such as brazing and welding, are a common application in industry,
especially in the automotive industry. These processes are the key to lightweight
and efficient design with regard to the automotive industry. There, laser brazing is used
mainly for visible joints due to the superior paint adhesion and surface roughness of
brazed joints compared to welds. As laser brazing is applied in the automotive industry
without using any fluxes or shielding gas, this leads to a difficulty in maintaining and
ensuring the quality of brazed joints.
