An assembly (1) for protecting an acoustic device comprises an expanded polytetrafluorethylene (ePTFE) membrane (3) and first and second polymeric substrates (2, 4) disposed on opposing sides (5, 6) of the membrane (3). The first substrate (2) is transmissive for laser light of a predetermined wavelength, and the membrane (3) is joined to the first and second substrates (2, 4) by first and second laser weld joints (9, 10) on the first side (5) of the membrane (3) and the second side (6) of the membrane (3), respectively, that are created in a single laser transmission welding step through the first polymeric substrate (2) towards the second polymeric substrate (4). The first side (5) of the membrane (3) may be at least partially absorbent for the laser light and the second side (6) may be at least partially transmissive for the laser light. This may be achieved by a color gradient from black to white from the first side (5) to the second side (6).

A process for room temperature substrate bonding employs a first substrate substantially transparent to a laser wavelength is selected. A second substrate for mating at an interface with the first substrate is then selected. A transmissivity change at the interface is created and the first and second substrates are mated at the interface. The first substrate is then irradiated with a laser of the transparency wavelength substantially focused at the interface and a localized high temperature at the interface from energy supplied by the laser is created. The first and second substrates immediately adjacent the interface are softened with diffusion across the interface to fuse the substrates.
