    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...

    Trevor Anderson, Jarvie Engineering Pty. Ltd.; Newcastle NSW Australia Australia
    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

    Further developments in laser beam sources as fiber and thin disk lasers allow deep penetration welding with unrivalled welding speeds because of their high brilliance. Thereby imperfections in the welding seam may occur - particularly humping as well as spatters. Visual and infrared high-speed videos show the location and the formation of the humps. The humping phenomenon during the high speed welding proc...

    Presented at PICALO 2008

    The increasing demand for improved fuel efficiency and reduced emissions has prompted the automotive industry to seek methods of reducing vehicle body weight by using materials with good strength to weight ratio, such as ultra-high strength (UHS) steels. Consequently, these steels have been the fastest growing weight reducing materials to be used in vehicle structures in the last decade, despite competition from aluminium alloys and composite materials. Laser welding of UHS steels, eith...
