Abstract
Comparative analysis of peculiarities of formation of pipe steel joints made by flash and resistance butt welding was made. It is shown by the investigations performed that the presence of a melt layer in a butt joint leads during upsetting to the development of an extensive zone of volumetric interaction, minimum distortion of leneage structure and insignificant decrease in metal density in the butt.
Keywords: flash-butt welding, resistance welding, melt, isotope, deformation
