The mechanical properties of steel structures are largely dependent on their operating conditions, with the operating temperature being a crucial factor. Welded constructions require even more attention as the welded joint and its surrounding areas are affected by changes in material during the welding process due to heat input. A study was conducted to test the base material and welded joint made of low-alloy carbon steel A516 Gr. 70 using the tensioning method at five different temperatures for the base material and one temperature for the welded joint. The results and comparative analysis were presented in graphical form in the article, and data analysis was carried out to draw conclusions. The study confirmed the wide range of applications of this type of steel and the reliability of structures made from it. The findings of this study can help engineers and designers to better understand the behavior of steel structures under different operating conditions and make informed decisions regarding their use in specific applications.
