A laser welding method and apparatus especially suitable for laser welding polymer articles having low light transmissivity at the wavelength used for laser welding. A protective region is provided to the articles being welded that is designed to protect the irradiated surface from degrading during welding.
L'invention divulgue un appareil et un procédé de soudage au laser qui convient particulièrement bien au soudage par laser des articles en matière polymère ayant une faible transmissivité à la lumière aux longueurs d'onde intervenant dans le soudage au laser. Une zone de protection est posée sur les articles en cours de soudage, celle-ci étant conçue pour protéger la surface irradiée afin d'éviter sa dégradation pendant l'opération de soudage.
