Carrying out quality control of welding directly during its performance allows timely elimination of identified deficiencies. This shortens the time for making quality welded joints and reduces material costs by making timely adjustments to the welding process. The AE method is also actively used for these purposes. Various standards of high-quality welded joints are being developed based on registered AE signals. Such studies are also conducted at the E.O. Paton Electric Welding Institute of the National Academy of Sciences of Ukraine. This becomes particularly relevant in a period of rapid rehabilitation and repair of industrial sites in modern conditions, and the challenge for professionals is to ensure reliable and cost-effective detection of weld defects. The article examines the results of the first stage of the application of AE systems EMA during the electric welding process using different equipment adjustment modes. The peculiarities of the occurrence of AE signals and the distribution of their parameters during welding and cooling of samples are analyzed. Necessary refinements of approaches to further research have been determined, and changes to the software of AE systems EMA are necessary. 13 Ref., 15 Fig.
