METHOD AND APPARATUS FOR INDUCTION FUSION OF CYLINDRICAL PRODUCTS Russian patent published in 1999 - IPC

FIELD: welding and fusion, possibly at continuously applying fused charge onto cylindrical surfaces of induction fused parts. SUBSTANCE: charge is preliminarily metered and fed to heating zone directly between branched portions of inductor. Preliminary metering is carried out according to designed thickness of charge poured onto article in dependance upon radius of welded product and rest angle of charge. Apparatus for metering charge is provided with accumulating hopper engaging with metering device. The last is mounted on eccentric axle and it is in the form of drum adjusted according to controllable gap relative to accumulating hopper and provided with synchronous transmission mechanism connected with rotation drive of welded product. Guiding funnel is secured between product and metering drum. EFFECT: enhanced accuracy of charge metering, enlarged manufacturing possibilities. 2 cl, 3 dwg
