description: In the work, studies were carried out to improve the quality of welded joints of duplex steels based on the analysis of modern scientific articles. A literature review on the welding of duplex steels and an analysis of research papers on the use of various technologies to obtain high-quality welded joints have been carried out. The analysis of the mathematical model for construction in the COMSOL MULTIPHISYC software package was carried out. A review of LTC and the application of laser technologies was carried out. An experiment was carried out on the influence of laser welding modes on the properties of a welded joint made of duplex steels. The analysis of the defects arising in the course of welding is carried out. Practical recommendations are given to reduce defects in a welded joint. The results of experimental studies are presented. Recommendations are given for optimizing the process of laser welding of duplex steels. The research work was carried out as part of the certification of welding technology under the programâACST-98-10431 Â«Technological instruction for laser pulsed welding of DDT products,ID: ISAT.25290.00002Â».
