Abstract
A method welds together two layers within a multi-layer assembly Laser light is directed through an outer layer of the assembly that allows transmission of the laser light from its outer surface to at least within the vicinity of its inner surface substantially without any absorption of energy from the laser light, towards a layer including an absorbent component, corresponding to a portion thereof. The absorbent component is capable of absorbing laser light within a given wavelength range thereby creating a welded area between a surface of the layer having the absorbent component and the surface of a layer facing the layer having the absorbent component while other layers remain unwelded.
