    Lightweight design constructions are dominated by a mix of various materials, whereas aluminum and steel alloys play an important role especially for series production with high unit numbers. Plastics and especially fiber reinforced plastics offer a very high potential for lightweight design constructions. Thus they gain more and more importance especially ...

    Presented at ICALEO 2013

    Quasi-simultaneous laser welding (QSLW) of polymers is widely known laser joining technique. Traditionally joining of polymers has been done by using lasers of around 1 µm wavelength. With this wavelength the pair of polymers to be joined needs to be transparent and absorbing, usually clear and b...

    Laser welding of polymeric products has been manufactured for more than 20 years. During that time polymer welding has developed a lot. In spite of that, there are still some limitations in applying the process to the industry. Typically welding has been made in lap joint configuration with black and clear parts because of optical ...

    Presented at ICALEO 2013

    In order to guide cooling air through turbine blades, bore holes with 500-800 microns diameter need to be drilled into the blades. The tolerance of the bore hole diameter must not exceed a range of about 10-30 microns so that a constant air flow capacity can be guaranteed. For the determination of the bore hole diamet...

    Rotation sintering, also known as slush molding, is used to manufacture molded skins, such as cockpit or door interior panels for cars. At present, approx. 80 percent of molded skins are manufactured using electroforms due to the complex free-form surfaces, and surface structures such as leather graining. The manufacture of these electroforms is time-consuming and expensive. The aim is to replace conventional electrofor...

    Presented at ICALEO 2013

    The paper reports the research of laser drilling technology by ns pulse laser for purpose of making cooling holes with thinner recast layer or even without recast in aero-engine. In research we employ diverse modes in making holes in nickel-based alloy samples. The first way is making holes with low power high frequency ns pulse laser in scanning mode of removing the material layer by layer, the second one is making holes with ns width pulse train laser in percussion mode, the third is ...

    Presented at ICALEO 2013

    Monitoring both near and far field laser beam parameters is extremely helpful in understanding the quality of a laser process. The measurement of such parameters has not been practical to date due to the required disruption of the process beam in order to make the measurement. A significant quality control enhancement could be realized if one could monitor both near and far field patterns of the laser system during the process if it could...
