    Presented at ICALEO 2010

    With the advancement of high power fiber delivery lasers, remote laser welding becomes a reality and more and more systems have been introduced into production lines. Remote laser welding takes the advantages of less mechanical movement and better accessibility of the beam to the workpiece, thus fast processing speed can be achieved. In most cases, remote laser weldi...

    Presented at ICALEO 2010

    The existing problems of weld defects in welidng zinc coated steels in a overlap situation are present in the automotive industry. The root cause is the different melting temperature of zinc and steel. Zinc vapourises already at 900C versus steel melts at 1500C. The result if not taking care of the outgasing are pinholes and crates in the weld seam. Extensive researc...

    Presented at ICALEO 2010

    The occurrence of focus shift in high power fiber laser welding has been reported. The small percentage of laser light absorbed in the optical elements of the welding head leads to a thermal focus shift. Contaminations on the optical surfaces are enhancing the absorption and thus the focus shift. So, o...

    Presented at ICALEO 2010

    With the advent of very high power fiber and disk lasers, choosing the right optical material for the application is vitally important. The best optic for an application is determined by a combination of factors about the application itself and the optic material properties. Important application factors include the laser power, laser type, and the users application. Material properties that the designer ...

    Presented at ICALEO 2010

    Disk laser is being used as a noble source in laser material processing area due to the high quality of the beam. In laser material interaction field, laser induced plasma has been an interesting part because this inevitable phenomenon in the area is closely related with energy transfer. This plasma plume can diverge or converge the focusing laser beam. Absorption in the plasma block the energy transfer from the laser beam to the target material. On the other hand converging beam enhance the energ...
