Device for alignment of cylindrical workpieces for magnetic-discharge welding
First Claim
1. A device for alignment of pipes for magnetic-discharge welding, comprising aligning disks installed on butt faces of an induction heater, characterized in that the device is provided with an external aligning sleeve (2) and an internal aligning sleeve (3) installed in the induction heater (1) coaxially and overlapping each other, the external aligning sleeve (2) being made of a non-polaraizable dielectric material and provided with a ledge (4) on the outer surface thereof, to which one of the aligning disks (5) abuts to lock the external aligning sleeve (2), while the internal aligning sleeve (3) is made of a non-magnetc material having low conductivity and provided, on the inner surface thereof, with step-like shaped through slots (7) and, on the outer surface thereof, with another ledge (6) limiting the depth to which the internal aligning sleeve (3) can be introduced into the external aligning sleeve (2);
- the internal sleeve (3) is locked in relation to the induction heater (1) by means of a second aligning disk (10) contiguous to the another ledge (6).

Abstract
A device for alignment of cylindrical workpieces for magnetic-discharge welding is provided with external and internal aligning sleeves (2,3) installed in an induction heater (1) coaxially and overlapping each other; the external aligning sleeve (2) is made of a non-polarizable dielectric material and features a ledge (4) on the outer surface thereof so that it can be locked by one of the aligning disks (5); the internal aligning sleeve (3) is made of a non-magnetic material having low conductivity and provided, on the inner surface thereof, with step-like shaped through slots (7) and, on the outer surface thereof, with a ledge (6) limiting the depth to which the sleeve (3) can be introduced into the external aligning sleeve (2); the internal aligning sleeve (3) is locked in relation to the induction heater (1) by means of a second aligning disk (10) contiguous to the ledge (6).
