    Although laser cladding was developed thirty years ago, it has only been in the last ten years that research groups and companies have begun to exploit this technology to produce fully dense, near-net shape components with metals through techniques such as DMD, DMF, Laser Consolidation, or LENS. In order to produce components with fine features, it is necessary to provide prop...

    Laser welding has been widely accepted in many industries. Commercial systems are now available to laser weld steel coils end-to-end for continuous processing in steel mills. These systems compete with more traditional flash butt and resistance seam welding systems. This paper will describe the technical requirements for a coil joining weld, in terms of welding time and weld properties, and compare the c...

    John Stackhouse, Winbro Group Technologies; Coalville UK
    Presented at ICALEO 2005

    Turbine engine manufacturers are employing Laser Systems to drill,ablate, cut, weld, clad and mark critical components used in both aircraft and industrial gas turbines. Details of these techniques are discussed and explanations of the various Technology Modules such as DOF (drilling-on-the-fl ), probing, SPC and breakthrough detection are given. Turnkey solutions employing Robotized loading and unloading of workpieces are discussed. The use of YAG, Q-switched, CO2 and other Laser power sour...

    Presented at ICALEO 2005

    Robot-based remote welding with solid-state lasers increasingly becomes an issue for automotive industry due to low process costs in comparison to spot welding or conventional laser welding. When talking about remote welding, very often the necessity of high beam qualities is emphasized, which can so far only be delivered by diode-pumped Yb:YAG disc and fibre lasers. However, industrially qualified and widely-used today are Nd:YAG rod laser...

    Welding and brazing are well known joining processes applied in many industries for decades. Using a laser as the principal source of energy to replace the oxy-fuel or arc processes is somewhat new. Although basic welding engineering principles must be carefully followed in order to achieve quality welds, they have sometimes been o...
