Title (EN) METHOD FOR ESTABLISHING GALVANIC BONDS BETWEEN AN INSULATED WORKPIECE AND WELDING ELECTRODES ELECTRODE ARRANGEMENT FOR THE IMPLEMENTATION AND UTILIZATION THEREOF
(FR) PROCEDE POUR ETABLIR DES LIENS GALVANIQUES ENTRE UNE PIECE ISOLEE ET DES ELECTRODES DE SOUDURE. DISPOSITION A ELECTRODES POUR SA MISE EN OEUVRE ET SON UTILISATION
Abstract: front page image
(EN)Use of loop electrodes with input and output of current to and from the working area where a heating current is supplied before the welding operation to remove the insulation. The requirements in such devices regarding the straight sections of the current passage differ according to weither it is heating or welding. Whereas for a sufficient heating a decrease of the straight section is necessary, such a decrease is undesirable for the welding. To meet these contradictory requirements, there is proposed an electrode with input of heating current (25a) and output of current (25b) relative to the working area, these two conductors having the same potential during welding.
(FR)Il s"agit de l"emploi d"electrodes a boucles avec amenee et depart de courant vers et depuis la zone de travail ou un courant de chauffage est amene avant l"operation de soudure pour enlever l"isolation. Les exigences dans de tels dispositifs quant aux sections droites de passage de courant different selon qu"il s"agisse du chauffage ou de la soudure. Alors que pour un chauffage suffisant une diminution est indesirable pour la soudure. Pour satisfaire ces exigences contradictoires on propose une electrode avec amenee de courant de chauffage (25a) et depart de courant (25b) relativement a la zone de travail, ces deux conducteurs etant mis, lors de la soudure, au meme potentiel.
