Abstract

A.PROCEDE POUR ETABLIR UN ARC ELECTRIQUE DE SOUDAGE A COURANT CONTINU, NOTAMMENT SOUS GAZ PROTECTEUR AVEC UNE ELECTRODE NON FUSIBLE A BASE DE METAUX LEGERS. B.PROCEDE CARACTERISE EN CE QUE, POUR ALLUMER L'ARC ELECTRIQUE, ON CHANGE PENDANT UNE COURTE DUREE LA POLARITE DE L'ELECTRODE ET DE LA PIECE.A.PROCEDE FOR ESTABLISHING AN ELECTRIC ARC FOR CONTINUOUS CURRENT WELDING, ESPECIALLY UNDER PROTECTIVE GAS WITH A NON-FUSED ELECTRODE BASED ON LIGHT METALS. B. PROCEDURE CHARACTERIZED IN THAT, TO LIGHT THE ELECTRIC ARC, THE POLARITY OF THE ELECTRODE AND OF THE PART IS CHANGED FOR A SHORT TIME.
