This paper represents an image-based tool for quantitative characterization of the dissolution behaviour of fused
tungsten carbides (FTC) in weld pool. For the metallographical
investigations with microscopic images, a method for automatic
detection of hard phases is proposed to quantify the amount and
distribution of FTCs in the matrix material. With this tool, the
dependence of the hard phase characteristic on the welding parameters was investigated.
