Sažetak
Global trend related to the increased demand for energy is followed by the development of contemporary materials and welding processes. Although there are different projections of future energy sources development (nuclear reactors, renewable energy sources, etc.), the European Commission estimates that the energy generated by combustion of different fuels in thermal power plants will be one of the most important sources for energy supply to households, industry, transport and other sectors. Such energy can be further used for production of electricity and heating, as well as for any other purpose. In addition to defi ned operating parameters set for materials used in thermal power plants, such as service temperature, pressure and extremely aggressive operating media in exploitation, there is also a demand for prolonged service life of such materials. While producing components for thermal power plants, joining of materials is unthinkable without modern welding processes. Since the welded joint is the weakest point in any welded product, the welding issues require special attention in all stages of components design, manufacture, maintenance and exploitation in thermal power plants. This paper elaborates welding process and pressure applied in welding of low-alloy and high-alloy steels, as well as of Ni-alloys that are used in manufacturing of thermal power plant components (T/P 23, T/P 24, T/P 91, T/P 92, etc.). Special emphasis is put on connection of scientifi c fi ndings from the fi eld of metallurgy and welding with the practical experiences, having in mind the constant necessity of achieving better quality and reliability of welded joints in components used in thermal power plants.
