A system for laser processing includes a plate assembly having a first plate, a second plate secured to the first plate, and a pressure chamber located between the plates, a connector extending into and in fluid communication with the pressure chamber, and a fixture having a first end attached to the second plate of the plate assembly, a second end having surface having at least one opening and shaped to fit a part to be retained and laser processed, and a conduit extending therethrough in fluid communication with the pressure chamber and the at least one opening. During use, a pressure generated by a pump may be communicated to the conduit of the fixture through the pressure chamber to provide pressure (e.g., a suction effect) at the opening(s) to secure the part in place, e.g., with respect to another part, so they can be laser processed.

A gas-permeable porous fluororesin membrane (4) made of a fluororesin is welded to a resin component (2) made of a thermoplastic resin using a welding horn (62) having a working surface (62p) adapted to be brought into contact with a work object and provided with a projection (62t). The working surface (62p) of the welding horn (62) is provided with, for example, a plurality of projections (62t). The plurality of projections (62t) may be arranged in a grid pattern on the working surface (62p).
