Abstract

L'invention concerne le soudage avec un faisceau laser. Elle se rapporte à un appareil qui comprend un corps ayant un passage pour le faisceau laser qui est focalisé en dehors du corps très près d'une partie terminale du passage. Un second passage débouche dans le premier et dirige un jet transversal de gaz protecteur qui entraîne le plasma formé au cours du soudage vers un orifice de la paroi opposée du premier passage. Comme la zone de soudage est pratiquement entourée par le corps, l'entraînement d'air par le jet transversal est minimal. Application à la réalisation de soudures profondes à l'aide d'un faisceau laser.
