Title
(EN) SYSTEMS, METHODS, AND APPARATUS FOR CONTROL OF WIRE PREHEATING IN WELDING-TYPE SYSTEMS
(FR) SYSTÈMES, PROCÉDÉS ET APPAREIL DE COMMANDE DE PRÉCHAUFFAGE DE FIL DANS DES SYSTÈMES DE TYPE SOUDAGE
Abstract
(EN)
Apparatus, systems, and/or methods for weld wire preheating are disclosed. Some examples of the present disclosure relate to welding-type systems that use one or more preheaters to heat welding wire prior to an arc and/or deposition on a weldment. The welding wire may have one or more characteristics. A preheating control may determine a governing characteristic of the one or more welding wire characteristics and establish a threshold temperature and/or target temperature based on the governing characteristic. The preheating control may further control the one or more preheaters based on the threshold temperature and/or target temperature, in order to avoid a deformation and/or degradation of the welding wire that would impact column strength, wire feeding, weld process stability, and/or welding consumable longevity.

La présente invention concerne un appareil, des systèmes et/ou des procédés de préchauffage de fil de soudage. Certains exemples de la présente invention concernent des systèmes de type soudage qui utilisent un ou plusieurs préchauffeurs pour chauffer un fil de soudage avant un arc et/ou un dépôt sur un ensemble soudé. Le fil de soudage peut avoir une ou plusieurs caractéristiques. Une commande de préchauffage peut déterminer une caractéristique de régulation de la ou des caractéristiques de fil de soudage et établir une température seuil et/ou une température cible sur la base de la caractéristique de régulation. La commande de préchauffage peut en outre commander le ou les préchauffeurs sur la base de la température seuil et/ou de la température cible, afin d'éviter une déformation et/ou une dégradation du fil de soudage qui affecterait une résistance de colonne, une alimentation en fil, une stabilité de traitement de soudage et/ou une longévité de consommables de soudage.
