The aim of this paper is to present the influence of differ-ent temperatures on the impact toughness of welded joint of high strength low-alloy steel. The results of impact tests for all three constituents of the manual arc welded joint of NN-70 steel at temperatures range from 20 °C to -100 °C are presented. It has been shown that impact tests of high-strength low-alloy (HSLA) steels at room and lower tem-peratures indicate that temperature significantly affects the toughness of high-strength low-alloy steels in the context that lowering the test temperature leads to creation of brittle fracture in the form of a successive decrease in total impact energy. This indicator is very important in the further design and exploitation of welded steel structures.
