Closed Systems Einzigartige Mobilität Geschlossene Systeme sturdy Photo: L&A Lasertechnik, Radebeul ALW The spacious working chamber of the ALW allows workpieces of up to 350 kg to be processed, e.g. in tool and mould construction. With the 4-axis-motion system, the parts get precisely positioned underneath the laser beam, either with the joystick or automatically. With the tiltable optics, workpieces can be welded at a variable angle whereby the laser beam remains optimally aligned to the joint Technical data Leica Trinocular with ocular for wearers of glasses, connection for CCD-camera Working chamber LxWxH in mm Working surface (WxD) in mm Max. workpiece weight Workpiece motion Scope of motion 800 x 850 x 500 600 x 600 350 kg, centrally positioned motorized via joystick X, Y: 180 x 180 mm, Z: 380 mm Mechanical dimensions LxWxH in mm Weight Electrical connection Multi-layer welding to re-shape an 8-cavity mould (Photo: Jutz Lasertechnik GmbH, Wien) 100 W 150 W 75 J 100 J 9 kW 10 kW 0.5 – 20 ms Single pulse –15 Hz –20 Hz 0.2 – 2.0 mm, can be continuously set 150 mm Adjustable power-shaping within a laser pulse User-specific operation with up to 128 data records Viewing system Repair of damaged contours on turbine flaps (Photo: L&A Lasertechnik, Radebeul) Laser Average power Pulse energy Peak pulse power Pulse duration Pulse frequency Welding spot diameter Focusing optics Pulse shaping Control > CNC control with CAD data input for automatic operation for manufacturing serial parts (WINLaserNC ) > Micro-welding aperture for welding spot-Ø < 100µm > Tiltable turntable with chuck for horizontal to vertical rotation > Coaxial lighting for optimal illumination of cavities in the workpiece > Magnetic workpiece bracket for free positioning of workpieces > TV system for demonstrating and observing the welding process

Closed Systems powerful Photo: D-Sensors GmbH, Stahnsdorf Untill now the ALW has been used mainly for repair and deposit welding on tools and moulds. The ALW 200/300 meets the increased demands of industries and trades-people to carry out ambitious welding jobs on materials such as Aluminium, precious metals, Titanium and sensitive alloys. Such jobs are in increasing demand, and in such areas the advantages of Alpha Laser’s new resonator concept are becoming visible. The new, stable steel construction of the ALW allows for high precision of the motion system, thus for extremely exact movement...
