Title (EN) METHOD FOR PRESS-WELDING OF PARTS WITH HEATING BY ELECTRIC ARC MOVING IN A MAGNETIC FIELD
(FR) PROCEDE DE SOUDAGE SOUS PRESSION DE PIECES PAR CHAUFFAGE A L'AIDE D'UN ARC ELECTRIQUE SE DEPLAÇANT DANS UN CHAMP MAGNETIQUE
Abstract: front page image
(EN)A method for press-welding of parts with heating by electric arc moving in a magnetic field provides for placing the parts (2, 3) coaxially with a working gap ($g(d)) between their end-faces, generating in the gap ($g(d)) the electric arc (6) bringing about the heating of the end-faces of the parts (2, 3). The steady component of the voltage on the arc (6) is measured and when it reaches its minimum value corresponding to the moment when the end-faces (2, 3) reach the plastic deformation temperature of the material, a pulse increase of the electric arc current is effected with subsequent bringing together of the parts (2, 3).
(FR)Un procédé de soudage sous pression de pièces par chauffage à l'aide d'un arc électrique se déplaçant dans un champ magnétique, consiste à placer les pièces (2, 3) de manière coaxiale avec un écartement d'usinage ($g(d)) entre leurs faces terminales, à produire dans ledit écartement ($g(d)) l'arc électrique (6) entraînant le chauffage des faces terminales desdites pièces (2, 3). La composante stable de la tension dans l'arc (6) est mesurée, et lorsqu'elle atteint sa valeur maximum correspondant au moment où les faces terminales (2, 3) atteignent la température de déformation plastique du matériau, une augmentation impulsionnelle du courant de l'arc électrique se produit, entraînant l'union desdites pièces (2, 3).
