Welding processes are influenced by many parameters. By applying multimodal data fusion of multichannel image data and signals of various welding parameter, the correlation of these and their influence on weld seam imperfections are investigated. The application of a multispectral area camera array enables a new approach on non-destructive testing particularly supported by the passive thermography. The results show the different cooling behaviour of several welding imperfections, such as porosity, and present the relation between incorrect welding parameters and imperfections.
