摘要： 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.

摘要： A laser shielding device interposed between the camera and the reflected light and is provided with a plurality of plates juxtaposed at an interval. Of the plurality of plates, an incident-side plate disposed on an incident side of the reflected light may be made larger in heat capacity compared to other plates disposed on the camera side of the incident-side plate.

摘要： The invention relates to methods for laser welding a first and a second workpiece portion with a laser beam that is guided using a laser machining head along a joining gap formed between the workpiece portions, in which method the laser beam is focused and a filler is lined up with the joining gap. At least one gap width of the joining gap of the workpiece portions to be welded is detected and evaluated along the course of the joining gap and compared with at least a first and a second gap measurement. If a detected gap width is within the first gap measurement, the feeding of the filler to the joining gap is stopped and a beam profile of the laser beam is set with a point or annular focus, and if a detected gap width is within the second gap measurement, a feeding of the filler is actuated.

摘要： A method and system to manufacture workpieces employing a high intensity energy source that irradiates a surface of a workpiece to create a puddle and at least one resistively heated wire which is heated to at or near its melting temperature and deposited into the puddle as droplets. Preferably, a wire feeding device feeds the wire to the puddle, and a power supply supplies a heating signal to the wire where the heating signal comprises a plurality of current pulses and where each of the current pulses creates a molten droplet on a distal end of the wire which is deposited into the puddle.
