The word “laser” is often associated automatically, and quite rightly, with the word “precision”. However, it is also easy to make the incorrect assumption that “precision” is only associated with “small” or ”miniature” components. The new StarWeld Integral combines ROFIN's concept of manual welding lasers with an extremely spacious working chamber and high average power.
Maximum automation and minimum programming
One of the unique features of the StarWeld Integral system is that it can be used in three distinct operational modes:-
• As a manual welding laser having excellent ergonomic design
• As a joystick-controlled deposit welding laser
• As a high-precision CNC laser welding system
Incorporating four high-precision positioning axes, and with short set-up times and easy CNC programming, users can select as much automation as they desire, and perform the minimum of programming necessary. The large working chamber provides space for objects with an edge length of up to 500 mm. Motorised X,Y and Z axes are designed to move work pieces with a maximum weight of up to 500 kg quickly and precisely in all three planes, allowing rapid and accurate positioning of parts, from the most delicate to a heavy load
In addition the optical system within StarWeld Integral can be swivelled around 2 axes enabling processing of perpendicular surfaces, undercuts or deep grooves without the need to turn or tilt the work piece. The multi-function joystick and a large colour touch screen are designed for simple and intuitive set up and using the joystick mode provides many of the benefits of motorized control of the axes, without the need for CNC programming.
As an option, StarWeld Integral can be configured as an open system - laser class IV workstation – which can accommodate extremely large work pieces. With 200 W of laser power available, these features combined mean that the StarWeld Integral is suited for almost all laser welding applications in precision engineering, electronics, thin sheet metal or the tool and mould industry.
The StarWeld Integral is mainly used in the tool and mould industry to repair mould tools by adding welding wire onto damaged edges or surfaces. Material with hardness up to 60 HRc can be deposited onto all the most commonly used tool steels including 420 stainless steel (1.2083), H13 tool steel (1.2344) and many others. Rofin offers a complete training on the system and can provide welding rods in the range of diameters and materials to suit the injection mould tool industry.
Rofin offers a complete range of lasers including CO2, YAG, Vandate and Fibre Lasers. Rofin also provides solutions and systems for laser cutting and marking applications.
