Title (EN) METHODS AND APPARATUS TO PREHEAT WELDING WIRE FOR LOW HYDROGEN WELDING
(FR) PROCÉDÉS ET APPAREILS POUR PRÉCHAUFFER UN FIL DE SOUDAGE POUR UN SOUDAGE À FAIBLE TENEUR EN HYDROGÈNE
Abstract:
(EN) Methods and apparatus to preheat welding wire for low hydrogen welding are disclosed. An example apparatus to reduce hydrogen associated with a consumable welding electrode includes: a welding-type power source configured to provide welding-type current to a welding-type circuit, the welding-type circuit comprising a welding-type electrode and a first contact tip of a welding torch; an electrode preheating circuit configured to provide preheating current through a first portion of the welding-type electrode between a wire feeder supplying the welding-type electrode and at least one of the first contact tip or a second contact tip of the welding torch.
(FR) L'invention concerne des procédés et des appareils pour préchauffer un fil de soudage pour un soudage à faible teneur en hydrogène. Un appareil donné à titre d'exemple pour réduire l'hydrogène associé à une électrode de soudage consommable comprend : une source d'alimentation de type soudage conçue pour fournir un courant de type soudage à un circuit de type soudage, le circuit de type soudage comprenant une électrode de type soudage et une première pointe de contact d'une torche de soudage; un circuit de préchauffage d'électrode conçu pour fournir un courant de préchauffage à travers une première partie de l'électrode de type soudage entre un dispositif d'alimentation en fil alimentant l'électrode de type soudage et la première pointe de contact et/ou la seconde pointe de contact de la torche de soudage.
