The invention an arc welding solid wire whose surface comprises copper plated film, wherein the elastic limit ratio (elastic limit/tensile strength) of the wire finally produced is controlled in the range between 50 and 88 % by installing three to eight elastic limit ratio control vertical rollers and three to eight elastic limit ratio control transverse rollers which have a ratio D/d equal to 40 to 60, following coil control vertical and transverse rollers after final drawing.
L'invention concerne un fil plein de soudage dont la surface comprend un film plaqué en cuivre, et caractérisé en ce que l'on régule le seuil de plasticité du fil fini (rapport limite d'élasticité/résistance à la traction) pour qu'il se situe entre 50 et 88 %, en installant trois à huit rouleaux verticaux de régulation du seuil de plasticité et trois à huit rouleaux transversaux de régulation du seuil de plasticité, selon un rapport diamètre rouleau/diamètre fil (D/d) se situant entre 40 et 60, après les rouleaux verticaux et transversaux d'enroulement, après étirage final.
