<p>A device for centring cylindrical parts during magnetic pulse welding comprises external and internal centring bushings (2, 3) mounted inside the inductor (1) and oriented axially and overlapping each other, the external bushing (2) being made of a non-polarizable dielectric, being provided with a protrusion (4) on its external surface and being fixed with one of a number of centring discs (5), whereas the internal centring bushing (3) is made of a non-magnetic material with a low electrical conductivity and is provided on its internal surface with stepped, profiled through-slots (7) and on its external surface - with a protrusion (6) for limiting its entry into the external bushing (3). The securing of the bushing (3) in relation to the inductor (1) is effected by means of a second centring disc (10) adjoining said protrusion (6).</p> |
