Laser Systems for High-Power Materials Processing Applications Superior Reliability & Performance Direct-Diode Industrial Systems

Products HighLight series of high power direct diode laser (HPDDL) systems are simple to use and have a proven track record in industrial environments. These systems consist of a light weight, rugged laser head, a user friendly control unit with a Graphical User Interface (GUI) and a chiller. The compact size of the laser enables mounting the head on a robot or a gantry type system. The lightweight and rugged design is employed in production sites worldwide processing everything from small hand tools to massive steel shafts and heavy truck axles. The types of industrial production processes include...

Focus on Heat Treating Heat treating a surface with a laser is as simple as point the laser, heat the surface, and let it cool. HPDDL’s are ideal for performing laser-transformation hardening in a manufacturing environment because of the superior heat treat characteristics, the flexibility of the process, the compatibility with a lean manufacturing environment, and fast cycle time for processing the parts. When comparing yields, operating expenses, and environmental impact, this method is the most cost-effective laser heat-treating process.With their high edge definition and 805 or 940 nm wavelength,...

Focus on Welding HPDDL provide a high quality, conductionstyle weld in most metals. Typical autongenous laser welding requires very tight fit-up, similar to E-beam processing. The gap fit-up tolerance required is approximately 3% of thickness, which eliminates the use of most low-cost parts because they need a machined interface fit-up. Therefore, the industry defaults to TIG and PTA processes in order to achieve a robust production weld process. HighLight HPDDL achieve process speeds 3X faster than Tungsten Inert Gas (TIG) or Plasma Transfer Arc (PTA) laser welding. Because the HPDDL weld nugget...

Focus on Brazing The HPDDL line spot makes feeding wire into the laser beam very easy. No expensive vision systems or precision alignment devices are required. The long beam, which is suitable for conduction- mode weld, "wets out" the weld and produces excellent weld bead profiles. For body-in-white brazing, our HPDDL create excellent braze joints that require no rework after brazing. Advantages • Lower cost • Low maintenance • Non-plasma process • Splatter significantly reduced • Zinc fuming and sooting reduced • No MIG/TIG fouling • Lower heat input • Faster brazing process Industry Applications...

Advantages • Non-contact, fast, flexible and no vibration • Any desired weld-seam contour or large area • Easily automated and high process stability • Low thermal stress and low mechanical stress • Control of melt geometry Industry Applications • Electronics Housings • Automotive Parts • Fuel Pumps Focus on Other Industrial Processes HighLight HPDDL provide excellent results in a variety of surface engineering applications, such as large-area paint stripping. These lasers feature a line beam, which enables thermo-mechanical stressinduced dislocations and then physical ablation over a large area...
