  • ICALEO 2013 Paper #1001 (Sensor System for Spatially Resolved Observation of the Melt Pool in Selective Laser Melting)

    Sensor System for Spatially Resolved Observation of the Melt Pool in Selective Laser Melting
    Authors:
    Ulrich Thombansen, Fraunhofer Institute for Laser Technology ILT; Aachen USA
    Andrei Diatlov, Rwth Aachen University Chair of Lasertechnology (Llt); Aachen Germany
    Presented at ICALEO 2013

    In selective laser melting, products are generated by selectively melting powder layer by layer. The amount of energy coupled into the powder results in a melt pool that can be observed by detecting its thermal emission.
    A sensor system acquires information during processing through a scanner based manufacturing system for selective laser melting. The coaxially coupled detection system is compris...

    Presented at ICALEO 2013

    If the powder bed laser melting process is now widely used, the fusion process is not clearly understood yet. Particularly, it is important, formation of spatters and melt pool stability has not been analysed. From previous works, thermo convective effects have evidenced but should be more inv...

    Christoph Turner, RWTH Aachen University; Aachen Germany
    Presented at ICALEO 2013

    The laser beam GMA hybrid process has, already since the beginning of the year 2000, been used for applications in shipbuilding. At that, linear welds have been welded as butt welds and also as fillet welds as a solid weld connection in the flat position (PA). It is, therefore, the logical consequence, to extend this spectrum to other welding positions, particularly due to the easy handling of the we...

    Presented at ICALEO 2013

    The regular formation of drops, called the humping effect in laser welding has been studied and analyzed by several research groups, however preferably for the top surface. Humping phenomena at the root have been much less investigated, even though they might have similar impact on the mechanical properties of the weld. Root humping is studied based on synchronize...

    Presented at ICALEO 2013

    NiTi shape memory alloy has played a leading role on recent development of innovative biomedical devices, sensors and consumer products. However, its high material cost, low formability and poor weldability are critical shortcomings that hinder its further applications. To reduce the material cost, manufacturers prefer to use Nitinol only for the critical part and other alloys for the rest of the component. ...

    Presented at ICALEO 2013

    In keyhole laser welding of pure nickel and martensite stainless steel, one of the problems is porosity formation in the weld metal. Since almost of the shielding gases, except hydrogen, can hardly be dissolved in nickel after solidification, the gas involved into the keyhole during th...
