Presented in this paper is the effect of plasma welding (hardfacing) and carbides presence on the occurrence of cracks and micro-cracks in the welded layer. The reasons behind this phenomenon were analyzed and explained. In addition, the plasma welding technology with all the necessary data such as welding parameters is shown for the case of a non-damaged tooth of a machine used for milling of marble. Welded layer with a significant amount of tungsten-carbide was applied onto new, non-damaged tooth in order to improve the characteristics of the surface layer of the base material, by increasing its hardness which leads to increasing of wear resistance and impact toughness. After welding, tooth was cut using an electrical discharge machining (EDM) for the purpose of examinations of the ap-plied surface layer in different locations throughout welded joint. Macro and micro-structure analysis aided in determining the characteristics of the surface layer. The nature and causes of cracks and ...micro-cracks were analyzed, in order to provide a better solution to avoid cracks occurrences, as well as in determining of their potential effect on the integri-ty of the tooth as a whole.
