Title
(EN) JOINING METHOD
(FR) PROCEDE DE SOLIDARISATION
Abstract
(EN)
A joining method directs polychromate, non-coherent electromagnetic radiation (14) through a radiation transmitting material (16) to an absorbing material (18) that absorbs the radiation with the generation of heat. The heat is used to heat a bond line (20) formed from the transmitting material (16) and a substrate (18) sufficiently to bond the transmitting material (16) and substrate (18). A radiation filter (22) of the same material as the transmitting material is used to reduce effectively unwanted absorption (and heat) in the transmitting material (16). Radiation focusing, masking, transmitting plastic cooling, bond line component drying, double pass welding, and additional bond line pressure are used to improve the bond of the resulting manufacture. A moving double radiation source units improves welding speed at least 5-6 times that of a moving single radiation source unit.
(FR)
La présente invention concerne un procédé de solidarisation consistant à diriger un rayonnement électromagnétique, non cohérent et polychrome (14), via un matériau (16) transparent au rayonnement, sur un matériaux absorbant (18) qui absorbe le rayonnement avec dégagement de chaleur. Cette chaleur sert à chauffer une ligne de liaison (20) constituée entre le matériau transparent (16) et un substrat (18) de manière suffisante pour solidariser le matériau transparent (16) et le substrat (18). Un filtre de rayonnement (22), réalisé dans le même matériau que le matériau transparent, permet de réduire sensiblement l'absorption (et la chaleur) indésirable dans le matériau transparent (16). La focalisation du rayonnement, son masquage, le refroidissement du plastique transparent, le séchage du composant de la ligne de liaison, le soudage double passe et une pression supplémentaire sur la ligne de liaison contribuent à améliorer la solidarisation des objets ainsi fabriqués. L'emploi d'unités mobiles à double source de rayonnement permet d'obtenir une vitesse de soudage d'au moins 5 ou 6 supérieure à celle obtenue avec une unité mobile à une seule source de rayonnement.
