description: The topic of the final qualifying work: The study of the properties of welded joints of new aluminum alloys ÐÐ35Ñ and 1939. Aluminum alloys have been used in bridge structures for more than 70 years. Aluminum has been used in various ways in hundreds of bridge structures around the world, and most of them remain in use today, including some for more than 50 years. Although aluminum alloys are still not considered a standard for bridge structures, they have a lot to offer for such applications and continue to be used where their low weight, high strength-to-weight ratio and excellent corrosion resistance meet service requirements and justify additional initial costs. This work is devoted to the study of the properties of the base metal and welded joints made of new aluminum alloys ÐÐ35Ñ and 1939 to determine the possibility of their use in building structures, in particular in the structures of pedestrian and road bridges.FSW modes were selected for aluminum alloys ÐÐ35Ñ and 1939 and tests were carried out: for static stretching; determination of hardness; for impact strength. Based on the test results, comparative diagrams were constructed and the data analyzed.
