FIELD: technological processes.
SUBSTANCE: stocks are installed along line of their connection tightly to each other, and rotary welding tool that contains casing with support collar and working rod is inserted into initial section of connection point. While tool is moved along connection line, friction heat is generated and plasticised area of connected parts material is created. Welding tool is installed with longitudinal displacement in relation to normal line to welded surfaces along welding direction. Value of longitudinal displacement of welding tool in relation to normal line to welded surfaces is selected within the limits of 0.5÷5.0 of working rod diameter.
EFFECT: creation of welded seam that is uniform in structure, free of defects, tight and strong.
