AbstractThe 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.
Keywordsfine-grained structure, metal structures, weld seam, manual arc welding, arc discharge stability, mechanical properties, metal quality, dendritic grinding, impulse action, electromagnetic field, metallographic studies, macro and microstructure of samples, ferrite, dendrite.
