Abstract

L'invention concerne un procédé d'aide au soudage ou à la découpe à haute température consistant (a) à prendre un filtre de rayonnement lumineux transparent à la lumière visible et qui atténue le rayonnement lumineux à des longueurs d'ondes plus courtes que la lumière jaune, à interposer ce filtre dans le chemin de rayonnement lumineux provenant de la zone de travail qui ne porte pas de repères qui créeraient une émission de rayonnement lumineux dans la région jaune-orange-rouge du spectre, ou (b) à interposer un filtre polarisant dans le chemin de rayonnement lumineux, entre la zone de travail et l'opérateur, la direction ou les directions de polarisation du filtre étant conçues de façon à atténuer le rayonnement lumineux partiellement polarisé provenant de diffusion, de réflexion diffuse ou de réflexion spéculaire au voisinage de la zone de travail. L'invention concerne aussi un filtre polarisant utilisé dans l'étape (b) du procédé.
