Abstract

Instalatia confrom inventiei, este alcatuita din doua transformaroare de sudare, legate cu un pol comun la un electrod, în contact cu piesa de masa mica, iar la celalalt pol, la doi electrozi, ce se afla în cpntact cu piesa de masa mai mare si distantati între ei, astfel încît, comandîndu-se tensiunea pe primarul transformatoarelor prin niste contactoare statice cu unghiuri diferite de comanda, se obtine un curent de circulatie între zona dintre cei doi electrozi înainte de presarea pieselor, proportional cu diferenta celor doua unghiuri pîna în momentul cînd curentul, electric dintre cei doi electrozi se anuleaza, în continuare circulînd curenti electrici în zonele dintre piesa mica si electrozi, proportionali cu unghiurile, uniformizarea temperaturii în cele doua zone realizîndu-se prin comutarea succesiva a unghiurilor de la un contactor static la altul, dupa presare existînd posibilitatea corectarii unghiului, în scopul modificarii curentului în zona piesei-suport dintre electrozi.The installation according to the invention consists of two welding transformers connected to a common pole on an electrode in contact with the small piece, and at the other pole, on two electrodes, which is in contact with the larger piece and distancing each other so that by controlling the voltage on the primary of the transformers by means of static contactors with different angles of control, a circulation current is obtained between the area between the two electrodes before compressing the parts, proportional to the difference of the two angles up to the moment when the electrical current between the two electrodes is canceled, further circulating electrical currents in the zones between the small piece and the electrodes, proportional to the angles, the temperature uniformization in the two zones being realized by successive switching of the angles from one static contactor to another, after pressing there is the possibility of correcting the angle in order to change the current in the area of the support part t of electrodes.
