Title
(EN) WELDING TORCH AND CORRESPONDING MANUFACTURING METHOD
(FR) TORCHE DE SOUDAGE ET PROCÉDÉ DE FABRICATION CORRESPONDANT
Abstract
(EN)
The present invention relates to welding torches (1) that comprise a head (3) having a body (11) bearing an electrode (13), a source of electric current (27), a metal filler wire and a wire guide (19) guiding the metal filler wire to the electrode (13), the body (11) being obtained by additive manufacturing from an electrically conductive metal and the wire guide (19) comprising an insulating sheath (29) inside which the metal filler wire moves.
(FR)
La présente invention concerne les torches de soudage (1) qui comprend une tête (3) comportant un corps (11) portant une électrode (13), une source de courant électrique (27), un fil de métal d'apport et un guide-fil (19) guidant le fil de métal d'apport jusqu'à l'électrode (13), le corps (11) étant obtenu par fabrication additive en un métal conduisant l'électricité et le guide-fil (19) comprenant une gaine isolante (29) à l'intérieur de laquelle se déplace le fil de métal d'apport.
