The invention concerns a device and process for manufacturing formed metal tubing from a single sheet of metal with two longitudinal edges that are approximately rectilinear and parallel, in which the two longitudinal edges of the sheet of metal are welded together by means of a welding process involving at least one electric arc between at least one electrode (Ei) and the said sheet of metal upon contact with at least one ground (PMi), in which the plane of each grounding point (PMi) is positioned at a distance (e i) of between -5 mm and + 5 mm in relation to the plane of each corresponding electrode (Ei), the positive direction being the direction of relative displacement of the sheet of metal in relation to the said at least one electrode (Ei).
L'invention concerne un dispositif et un procédé de fabrication d'un tube métallique formé à partir d'une feuille métallique ayant deux bords longitudinaux sensiblement rectilignes et parallèles, dans lequel on soude, l'un avec l'autre, les deux bords longitudinaux de la feuille métallique au moyen d'un procédé de soudage mettant en oeuvre au moins un arc électrique entre au moins une électrode (Ei) et ladite feuille métallique au contact d'au moins une prise de masse (PMi), dans lequel le plan de chaque prise de masse (PMi) est positionnée à une distance (e i) comprise entre - 5 mm et + 25 mm par rapport au plan de chaque électrode (Ei) correspondante, le sens positif étant le sens de déplacement relatif de la feuille métallique par rapport à ladite au moins une électrode (Ei).
