Abstract

Appareil pour le soudage électrique. Le moteur 1 entraîne l'alternateur 4 qui par le redresseur 15 fournit le courant de soudure, ainsi que l'excitatrice 2, également à courant alternatif redressé par 3. L'inducteur 9 de 2 est alimenté par l'enroulement auxiliaire 6 de 1 à travers la diode 8 et par le transformateur d'intensité 14 inséré sur le circuit alternatif de 4. Il est prévu un circuit RC 19-20, des rhéostats de réglage 7, 10, 8 et des interrupteurs cI, c2, d, grâce auxquels à la fin de l'opération l'on peut passer progressivement du courant normal à un courant moyen, puis de ce dernier à zéro. Elimination des cratères d'extrémite des cordons de soudure.Apparatus for electric welding. The motor 1 drives the alternator 4 which, via the rectifier 15, supplies the welding current, as well as the exciter 2, also with alternating current rectified by 3. The inductor 9 of 2 is supplied by the auxiliary winding 6 of 1 through the diode 8 and by the current transformer 14 inserted on the alternating circuit of 4. An RC circuit 19-20 is provided, setting rheostats 7, 10, 8 and switches cI, c2, d, thanks to to which at the end of the operation it is possible to pass gradually from the normal current to an average current, then from the latter to zero. Elimination of end craters from weld seams.
