A process for laser welding together a laser beam transparent polyester article and a laser beam opaque polyester article. The method limits the use of a laser beam at an energy level not greater than 100 W at a scanning speed not greater than 1000 cm/min., thus causing the articles to be welded together and maintaining a high weld strength.
La présente invention concerne un procédé pour souder au laser un article en polyester transparent au faisceau laser et un article en polyester opaque au faisceau laser. Ce procédé limite l'utilisation d'un faisceau laser à un niveau d'énergie inférieur à 100 W et à une vitesse de balayage inférieure à 1000 cm/min., ce qui permet de souder les articles l'un à l'autre et de maintenir une grande résistance de soudure.
