The article presents the results of an experimental study of the effect of an additional pulse-quasi-harmonic voltage with a frequency of 40 kHz on the structure of welded joints, the technological properties of a DC arc discharge in manual arc welding with covered electrodes. Obtaining a fine-grained structure of a welded joint is one of the conditions for increasing its technological and strength properties, and the operational reliability of the manufactured product as a whole.
