    Laser brazed seams are nowadays well established in automotive industry for joints which must fulfill high quality standards. Joints located in direct visible areas of the car body, like the connection between roof and side-panel or the trunk-lit, must be manufactured without any failures like pores or spilling. To achieve this goal, system technology is subject to high accuracy requests on the one hand; on the ...

    A real-time, adaptive control and optimization system for laser flame cutting of thick plates of mild steel has been developed. The proposed system consists of two subsystems: a process monitoring system and a control and optimization system. The first subsystem aims at the on-line observation of the process status and corresponding cut quality. Since the different cut quality characteristics cannot ...

    Novel Beam Analysis Applications and Hardware
    Authors:
    Thomas Kugler, Laser Mechanisms, Inc; Farmington Hills MI USA
    Presented at ICALEO 2009

    Off-the-shelf beam analysis systems work very well in investigating and measuring collimated laser beam spatial profiles, focus spot spatial profiles, and the waist caustic. These standard systems have some shortcomings, however, related to viewing very small focus spot sizes at any wavelength, but especially at 10.6um. Another problem that these beam analysis systems can solve is alignment of optics and other components that can be damaged by high power beams if improperly set-up. This presentation will investigate the use of novel but simple imaging ...

    New Low-cost CO2 Beam Profiler Eliminates Need for Acrylic Mode Burns
    Authors:
    Lawrence Green, Ophir-Spiricon, Inc; Logan UT USA
    Presented at ICALEO 2009

    Acrylic Mode Burns have historically been universally used because they are the lowest cost alternative to the budget-minded end user. This method, however has been cited for producing dangerous, cancer-causing airborne materials, and is not a real time technology. On the other hand, Real-time beam profiling has been historically too expensive for the average user to acquire. We discuss a new technology that enables the design of a new low-cost real time CO2 high power beam profiler that is within reach of almost all end-users. This design do...

    Overcoming Limits in Processing of Advanced Material Geometries
    Authors:
    Henk Kettelarij, Philips Applied Technologies; Eindhoven Netherlands
    Presented at ICALEO 2009

    Standard laser processing technologies available on industrial scale often cannot fulfill specific requirements for processing advanced material geometries. A number of dedicated hardware and software solutions to overcome these limitations have been developed within Philips Applied Technologies. In this presentation some of these developments will be discussed. Maximizing processing speed for accurate micromachining of funnel shaped holes requires in depth knowledge of scanner dynamics. By carefully designing scanner tracks with...

    High Pulse Energy (HPE) Picosecond (ps) lasers are effective tools for processing a wide range of materials ranging from brittle samples that exhibit chipping/cracking to metals or composite materials such as the novel thin film solar cell material, Copper indium gallium selenide (CIGS), which suffer thermal deformation from long pulse laser processing. Mechanically machining me...

    Presented at ICALEO 2009

    Laser Assisted Machining (LAM) of ceramics is an important area of research concerning the improvement upon conventional diamond grinding machining processes. The problems associated with the machinability of these advanced ceramic materials, specifically silicon nitride (Si3N4), have already lead to previous research work done with LAM. Utilizing the advent of high power fiber diode lasers, current research can now be completed outside the realm of traditional lasers such...

    Authors:
    Frank Vollertsen, BIAS GmbH; Bremen Germany
    Claus Thomy, BIAS GmbH; Bremen Germany
    Presented at ICALEO 2009

    Laser MIG hybrid welding was recently suggested as a feasible process for joining of aluminium to steel for both structural and tailored blank applications. In this process, the aluminium is molten to create a brazed bond to the zinc-coated steel sheet, which remains solid. To further investigate the effect of process parameters, laser power, MIG arc power, wire feed rate, welding speed and arc position relative to the abutting edges were varied for the case of butt joints of aluminium alloy AA 6...
