  • Laser Beam Welding
    Laser welding is a high energy beam process and in this regard is similar to electron beam. With that exception they are unlike one another. The energy density of the laser is achieved by the concentration of light waves not electrons. The laser output is not electrical, does not require electrical
  • Fiber Laser Welding of High Integrity Implantable Medical Devices
    , such as electronic chips, lower melting point plastics, and organic materials. Properly selected laser beam characteristics, such as diameter of the beam and energy distribution within the focused spot in welding area, may significantly improve welding process increasing yield during production
  • Thermography Enhances the Capabilities of Laser Transmission Welding (.pdf)
    the temperature distribution within the surface of a welded polymer. Variations of the laser beam intensity distribution are altering the temperature field. An analysis of the temperature-time-flow within the welding zone provides information with respect to the welding properties. Microsoft Word - 2008-040
  • Laser Welding of Plastics (.pdf)
    , polyethylene, clear. polycarbonate, nylon and natural PET. The underlying material is ideally black, colored. using carbon black, or pigmented to some degree. Welding usually occurs away from the focus of the laser, and the required weld strength. can be tailored by using different beam sizes
  • Laser Welding of Thermoplastics
    . In this method the absorption of beam energy is significantly enhanced. through use of dyes and pigments at the weld point. The second method known as `Infrared Laser Penetration Welding Technique' uses direct. infrared laser energy absorption in the overlapped plastics to be joined. This method
  • Laser Welding Plastics Using a Fiber Laser

Summary. Contour Welding: Fiber lasers have now matured into exceptionally. In contour welding, the laser
  • Fiber Laser Welding of Clear Plastics
    . occurs at the joint interface. Plastics welded by. conventional thermal welding techniques can also. be laser welded. Specialised plastics are now. becoming available that appear black but. transmit enough of the laser beam to allow them. to be used as the upper component of a. transmission welded
  • Electron Beam Welding
    can be greater and the width of the weld smaller than even laser beam type welding processes. Electron beam welding requires a vacuum atmosphere to prevent absorption of the electrons by air.
