In industrial practice, we often encounter problems with the wear mechanism of tools and tool parts in applications carried out at elevated temperatures. These are most characteristic of non-ferrous metal casting, extrusion, forging and plastic injection moulding processes. The thesis focuses on the production of three different batches of H11 welded tool steel with Capilla 733 compatible welding material and the determination of the interaction between material welding technology and heat treatment on the final hardness developed, in conjunction with the development of tempering diagrams to predict the developed properties. The result of the thesis includes optimal recommendations on the influence of the number of welds and the tempering temperature to maximise the hardness of the material and thus increase the wear resistance.
