Abstract
L'invention concerne le soudage à l'arc. Il est décrit un procédé de réduction de la formation d'ozone à proximité d'un arc électrique, caractérisé en ce que l'on disperse, à proximité de cet arc, en concentration convenable, de l'oxyde d'azote ou du chlore, ou toute autre substance réductrice d'ozone, ou un mélange de telles substances, pour provoquer une réaction de l'additif ainsi introduit avec l'ozone formé par radiations ultraviolettes à partir de l'oxygène présent. On réduit ainsi l'atmosphère toxique environnant le poste de soudage.
