FIELD: erection of pipe lines. SUBSTANCE: permanent magnetic field is created in zone of coupling the pipes and directive ferromagnetic particle flux is created in pipe. Ferromagnetic particles accumulate in clearance filling it under action of magnetic field. Then ferromagnetic particles are subjected to induction heating, thus causing surface fusion of pipes to be welded together over clearance. As a result, ferromagnetic particles bind parts being welded together with molten material of pipes being connected. EFFECT: enhanced reliability. 1 dwg
