However, because of their properties, care must be taken in order to determine suitable welding parameters. One way is to use the weld-heat-flow theory with the use of the weld-bead cooling time t8/5 and the recommendations of the standard EN 1011-2. The chosen weld parent material was high-strength S890QL steel with the filler welding wire G Mn4Ni1.5CrMo, which were used to produce a sound butt weld. Mechanical testing and a metallographic examination of the weld samples were carried out. The tensile test showed undermatching of the weld joint, with a satisfactory Charpy V notch toughness. The metallographic investigation revealed a microstructure variation in different areas of the weld joint. The highest values of the hardness HV10 were measured in the heat-affected zone"},{"@xml:lang":"sl","#text":"Poboljšana visokotrdna jekla se vsestransko uporabljajo pri gradnji jeklenih konstrukcij. Zaradi njihovih lastnosti je potrebna pazljivost pri določanju parametrov varjenja. Eden od načinov določitve parametrov varjenja je z uporabo teorije prenosa toplote in časa ohlajanja varka t8/5 z upoštevanjem navodil, podanih v standardu EN 1011-2. Za izvedbo sočelnega zavarjenega spoja sta bila izbrana visokotrdno poboljšano jeklo z oznako S890QL in dodajni material varilna žica z oznako G Mn4Ni1,5CrMo. Pri vzorcih zavarjenega spoja so bile izvedene mehanske in metalografske preiskave. Z nateznimi preizkusi je bila ugotovljena trdnostna neenakost z ustrezno vrednostjo V udarne žilavosti po Charpyju. Z metalografskimi preiskavami so bile odkrite spremembe v mikrostrukturi na različnih področjih zavarjenega spoja.
