(EN) ARRANGEMENT OF TWO PARTS MADE OF THERMOPLASTIC MATERIALS TO BE ASSEMBLED BY LASER WELDING
(FR) AGENCEMENT DE DEUX PIÈCES EN MATÉRIAUX THERMOPLASTIQUES DESTINÉES À ÊTRE ASSEMBLÉES PAR SOUDAGE LASER
Abrégé
(EN)
According to the invention the arrangement (10) of two parts (11, 12) made of thermoplastic materials to be assembled by a laser transparency welding method, a first part (11) that is transparent to a laser beam (F) being positioned on a second part (12) that absorbs the laser beam (F), is characterized in that the two parts (11, 12) comprise a welding interface (13) having a predetermined width (L1), so as to enable the clamping of the two parts (11, 12) against each other without interfering with the passage of the laser beam (F), and the cross-section (S) thereof is predetermined according to the properties of the materials of the parts (11, 12) to be assembled. Said width (L1) of the welding interface (13) is substantially equal to the sum of the width (L2) of a clamping area (15) and the width (L3) of a welding area (14).
(FR)
L'agencement (10) selon l'invention de deux pièces (11, 12) en matériaux thermoplastiques, destinées à être assemblées par un procédé de soudage laser par transparence, une première pièce (11) transparente à un faisceau laser (F) étant positionnée sur une seconde pièce (12) absorbante au faisceau laser (F), est caractérisé en ce que les deux pièces (11, 12) comportent une interface de soudage (13) de largeur (L1) prédéterminée, de sorte à permettre le bridage des deux pièces (11, 12) l'une contre l'autre sans interférer sur le passage du faisceau laser (F), et dont la section (S) est prédéterminée selon les caractéristiques des matériaux des pièces (11, 12) à assembler. Ladite largeur (L1) de l'interface de soudage (13) est sensiblement égale à la somme de la largeur (L2) d'une zone de bridage (15) et de la largeur (L3) d'une zone de soudage (14).
