Abstract
Peculiarities of flash butt welding of high-strength heat-hardening alloy 2219 were studied. It was shown that welded joint have no defects of the type of oxide films and delaminations. Optimal conditions for heating of the plastic deformation zone in upsetting were determined. A 15-20 % weakening of the heat-affected zone in the welded joints can be fully eliminated by postweld heat treatment (hardening and subsequent artificial ageing). Tensile strength of the welded joints is at a level of 93-95 % of that of the base metal.
