Title
(EN) SYSTEMS AND METHODS FOR CONTROLLING HEAT INPUT DURING SHORT-CIRCUITING TYPE WELDING PROCESSES
(FR) SYSTÈMES ET PROCÉDÉS DE RÉGULATION D'ENTRÉE DE CHALEUR PENDANT DES PROCESSUS DE SOUDAGE DE TYPE À COURT-CIRCUIT
Abstract
(EN)
Disclosed welding-type systems include a welding-type power source to generate output power for a periodic welding process that operates in an arc mode, an open circuit mode or a short circuit mode. A wire-feeder advances an electrode wire toward a workpiece. A controller adjusts the current to below a threshold value during the arc mode to result in the open circuit mode prior to occurrence of a short circuit event based on one or more welding process parameters. In some examples, the controller determines the occurrence of the short circuit event based on the one or more welding process parameters, and adjusts the current to rise above a second threshold level to adjust a heat generated in the welding wire in response to the occurrence of the short circuit.

L'invention concerne des systèmes de type soudage qui comprennent une source d'alimentation de type soudage permettant de générer une énergie de sortie pour un processus de soudage périodique qui fonctionne en mode arc, en mode circuit ouvert ou en mode court-circuit. Une tête de soudage fait avancer un fil d'électrode vers une pièce à travailler. Un dispositif de commande ajuste le courant au-dessous d'une valeur de seuil pendant le mode arc afin de conduire au mode circuit ouvert avant l'apparition d'un événement de court-circuit sur la base d'un ou de plusieurs paramètres du processus de soudage. Dans certains exemples, le dispositif de commande détermine l'apparition de l'événement de court-circuit sur la base du ou des paramètres de processus de soudage, et ajuste le courant afin de monter au-dessus d'un second niveau de seuil afin d'ajuster une chaleur générée dans le fil de soudage en réponse à l'apparition du court-circuit.
