Examination of degradation frequently repaired shearing and forming tools
 Izák, Josef ; Kubíček, Jaroslav (referee) ; Sigmund, Marian (advisor)
The diploma thesis is focused on the renovation of forming tools made of tool steel, their weldability and assessment of the quality of tool repairs. The damaged tool was a part of the cutter from the progressive cutting tool made of Caldie steel. We used micro TIG technology to repair the damage. A total of three types of additional materials were used and investigated to restore the geometry of the damaged edge. One of the main purposes was to evaluate the possibility of extending the life of tools and reducing the implementation of already inefficient repairs. A number of destructive tests were performed for the assessment - macrostructure, microstructure, hardness measurement and EDS analysis.
