Abstract
ENG: The article discusses the results of an experimental study of the microstructure of the weld metal of pipe billets subjected to vibration processing during the welding process. The experimental study was divided into the following stages: welding of longitudinal preformed pipe blanks using vibration action; production of thin sections and study of their microstructure in the zones of the welded seam; processing of the data obtained during the experiment. When studying the microstructure, special attention was paid to the areas of overheating and normalization, as the areas of the heat-affected zone most characterizing the quality of the weld. The tendency of change in the grain size of the weld metal at various frequencies of vibration used in the welding process, as well as in its absence, has been investigated. An important place in the study was given to the study of the degree of graininess of the studied structure.
