description: This work is dedicated to the study of the application of friction stir welding (FSW) in the production of heat exchangers from aluminum alloys. The tasks addressed during the research are: 1.Conducting a literature review on FSW technology and its applications. 2. Analyzing the technological process of friction stir welding. 3. Investigating the microstructure of welded joints. 4. Developing recommendations for optimizing FSW process parameters to improve welding quality. The work was carried out at Peter the Great St. Petersburg Polytechnic University, where a significant part of the factual material was collected: results of metallographic analysis and data from experiments on welding heat exchangers from 6061 aluminum alloy. Calculations and analysis of the microstructure of welded joints were performed, which allowed the identification of main defects and the proposal of measures for their elimination. As a result of the study, the high efficiency of the FSW technology in the production of heat exchangers from aluminum alloys was confirmed. The analysis showed that proper setting of process parameters allows for the creation of joints with a homogeneous microstructure and minimal defects. Based on the conducted research, practical recommendations for optimizing FSW parameters were developed, which will improve the quality and reliability of welded joints in the production of heat exchangers.
