    Current trends of intelligent products and controlled processes show an increasing need for long-living sensors. Metal thin-film strain gauges are suitable for monitoring mechanical loads over the entire lifetime of a component. However, existing manufacturing methods can only pattern these gauges on flat components and in large quantities...

    Experimental and Numerical Investigation on Short Pulsed Laser Welding of Stainless Steel Foils
    Authors:
    Hui-chi Chen, Singapore Institute of Manufacturing Technology; Singapore Singapore
    Presented at ICALEO 2013

    Today, there is a miniaturization trend in ultra-precision laser micro-welding applications. It is due to industrial products or components are being made smaller to save space or reduce energy consumptions. For example, laser hermetic sealing of implantable devices, microwave enclosures, batteries, sensors, etc. Since these devices are generally heat-sensitive, a proper control of energy input is necessary in order to avoid any heat damage. Laser micro-welding by pulsed laser systems ...

    Presented at ICALEO 2013

    The manuscript will address a 3D finite element modeling of a laser-assisted maskless micro-deposition process (aka micro laser sintering/cladding) where it is utilized in the production of micro-tracks composed of silver nano-particles. The model is established through a coupled heat conduction equation with strain/stress constitutive physics in the presence of a moving continuous or pulsed las...

    Robusteness of the Laser Melting Process
    Authors:
    Heiko Bruening, Bias - Bremer Institut Fuer Angewandte Strahltechnik Gmbh; Bremen Germany
    Presented at ICALEO 2013

    The use of laser technologies in material processing is wide spread in various manufacturing chains such as welding, brazing and cutting. Compared to other heat sources, the laser beam enables the allocation of a certain amount of energy in a specific time on a very small spot. For this reason, the laser especially is a suitable tool for material processing in micro range. Due to the fact that processes in micro range are rather influenced by forces related to the surface of the work piece than by forces related to their volume, a p...

    Presented at ICALEO 2013

    Carbon nanotubes (CNTs) have great electrical, mechanical and thermal properties compared to conventional materials. However, the naturally-bundled structure, lattice imperfections and impurities seriously limit their engineering applications. There have been attempts to use laser beams to remove the imperfections and impurities but the interaction between high-power laser pulses and CNT structures is still vaguely understood. In this work, the structural changes in single-walled...
