    Presented at PICALO 2008

    Laser surfacing, also known as laser cladding is an emerging technology that has gained a very important foothold in the area of industrial maintenance. Not only is the process providing new opportunities to resurface and extend critical component life, it is also facilitating the development of new products and opportunities that were previously considered impractical. The process is amongst the most expensive industrial coating processes available to the market today. However the last 8 years in Australia has seen process accept...

    Presented at PICALO 2008

    Within the solar cell industry a number of critical production processes are looking to the fibre laser to provide leading edge manufacturing solutions. In silicon based cells there is a need for silicon cutting and a novel process using a CW fibre laser has demonstrated superior cutting performance over existing technologies. In thin film based solar technologies there is a requirement for a number of scribes and cell edge deletion. The...

    Presented at PICALO 2008

    The plasma effect of the irradiated metal powder surface is a physical phenomenon which can give significant information about composition created in the melt pool and also it indicates range of temperatures involved in this process. It was observed that direct laser deposition (DLD) process is not completely free from plasma effects. Obviously it depends on laser cladding parameters, influence of shielding gas and deposited material, ...

    Presented at PICALO 2008

    Laser consolidation is a novel computer-aided manufacturing process being developed by the Integrated Manufacturing Technologies Institute of National Research Council of Canada (NRC-IMTI). This rapid manufacturing process produces net-shape functional metallic parts layer by layer directly from a CAD model by using a laser beam to melt the injected powder and re-solidifying it on the substrate or previous layer. As an alternative to the conventional machining process,...

    Presented at PICALO 2008

    Laser-Deposition of metals, such as titanium, stainless steel, nickel, and cobalt alloys, has found increasing application in repair and rapid manufacturing. The layerwise additive approach results in unconventional microstructures, and thus can also result in unconventional material properties. With a suitable choice and control of process parameters, the solidifying metal can cool at rates of over 1000°C/s, which can result in very fine microstructures. ...
