Title (EN) METHODS AND SYSTEMS FOR RESISTANCE SPOT WELDING USING DIRECT CURRENT MICRO PULSES
(FR) PROCÉDÉS ET SYSTÈMES DE SOUDAGE PAR POINTS PAR RÉSISTANCE AU MOYEN DE MICRO-IMPULSIONS À COURANT CONTINU
Abstract: front page image
(EN)Methods and systems for resistance spot welding using direct current micro pulses are described. One described method comprises comprising forming a weld joint by applying a plurality of direct current micro pulses to at least two pieces of materials through a first electrode and a second electrode.
(FR)L'invention concerne des procédés et des systèmes de soudage par points par résistance au moyen de micro-impulsions à courant continu. Un procédé comprend la formation d'un joint fixe par application de plusieurs micro-impulsions à courant continu sur au moins deux morceaux de matériau par l'intermédiaire d'une première électrode et d'une seconde électrode.
