Title:
電気スポット熔接ヘッド
Document Type and Number:
Japanese Patent JP4949082
Kind Code:
B2
Abstract:
A spot welding head is described wherein an electrical conductor (8) for connection of one electrode (2) connection to an electric transformer is guided into a tubular sheath (7) whose ends are rigidly connected to the rear ends of the supporting bodies (4) of the electrodes (2). This tubular sheath defines a substantially stiff loop portion which is configured and arranged so as to be substantially parallel and facing the annular path defined by the two electrodes (2) and the supporting bodies (4) thereof, in such a way that the two magnetic fields, one generated by electromagnetic induction caused by electric current flowing through the electric conductor (8) placed into the loop-shaped sheath (7), and the other generated by electromagnetic induction caused by electric current flowing through the electrodes and the supporting bodies thereof, substantially cancel each other out or anyway generate an overall magnetic field which is sensibly reduced and located forwardly with respect to the rear end of the welding head or anyway spaced forwardly away from the operator's body.
