                Well thought-out construction

                The core of the system is a basic unit which contains the axes (travel distance X up to 1,010 mm, Y up to 1,110 mm, Z up to 510 mm) and the supply elements as well as an individually configurable and modular interchangeable handling and feeding system. The systems are well-equipped for specific demands thanks to these flexible modules: 

              • The “Rotate” module for components that are introduced in the work space via a rotary table.
              • The “Slide” module for larger or longer components with multiple slots for parallel component feed and removal.
              • The “Powder” module for welding processes for repair with automated powder application.

              • Simass Rotate

              • This equipment variant is available as an option for the base unit. It has a permanently clocked or freely programmable precision turntable that moves the parts to be welded into the working space of the base unit. If required, it can be subsequently replaced with the modules “Simass Slide” or “Simass Powder” module. This way, your system can be adapted to all requirements in the future.

                Tailor-made for working on a rotary table

                The individually configurable rotary table with a maximum diameter of 1,500 mm can be equipped with a customised clamping system according to your needs. Supply lines for pneumatic connections are also available. Two separate areas on the rotary table also separate the loading and unloading area from the working area, allowing for convenient loading and unloading parallel to the welding process. 

              • Simass Slide

              • The Simass Slide is designed to weld big workpieces, such as large pipes. With its six numeric axes the system ensures maximum production capacity. The Simass Slide is equipped with three slides which can be moved into the working area separately.

                Hence, big workpieces can be loaded and unloaded during the
                welding process.  This means that downtimes are reduced and productivity is maximised.

                HORIZONTAL AND VERTICAL PROCESSING

                The three slides of the Simass Slide are equipped with three motorised rotation axes. The workpiece is clamped into the chuck which has a diameter of 315 mm. Since the rotational axes can be pivoted both horizontal and vertical processing are possible. Parts of up to 500 mm diameter and 1500 mm length can be operated in the standard version. For welding of materials as steel or aluminium a highly efficient fibre laser can be adapted in cw or pulse modus, depending on the application.

                    • SUPER PULSE TECHNOLOGY (SPT)

                    • Precision welding is a very challenging task for many metals used in industry. Super Pulse Technology (SPT), patented pulse modulation developed by Sigma Laser, offers a new, innovative opportunity to precisely weld such critical metal alloy materials.

                      Meets the highest challenges

                      Carbon content and cooling rates of molten baths are critical to steels’ welding suitability. SPT controls the melting bath dynamics and influences cooling speed, which can minimise the risk of problems which often occur, such as crack formation and problems with fusion.

                      Exact and appropriate to the material

                      High pulse peak power in pulsed systems may quickly lead to overheating of the metallic melt or welding seam defects. This is exactly where you can counteract the melting bath temperature with SPT thanks to individual settings.

                      In comparison to traditional laser welding systems, SPT can influence solidification morphology, including the rate of nucleation. This increases the plastic ductility of the compound with different materials such as titanium, aluminium or stainless steel. Of particular importance is combined pulse shaping and modulation when welding refractory metals. Excellent results can be achieved if the melt is supercooled using pulse modulation.

                • Individual equipment

                          Strict legal rules apply to operating laser welding systems – above all in the area of safety. Direct contact of the beams with eyes or the skin may result in serious injuries. Laser systems from Sigma Laser fully comply with the prescribed directives and DIN standards.

                          You should also take suitable measures in your company, such as with the use of protective clothing and the establishment of a clearly-defined laser control area. An overview of the most important measures:

                          • Marking the laser control area
                          • Use of ground markings and warning signs
                          • Setting up mobile or fixed laser shielding walls
                          • Immediate coverage of the process zone
                          • Protection by means of safety switch (interlock)
                          • Wearing protective clothing
                          • Certified training and appointment of laser protection officer

                        • Warranty and lamp break protection

                        • Unique warranty service

                          Thanks to the unique and special design of our lamps and their design as a two-lamp system with two separate power supplies, our lamp-pumped lasers offer a very long service life, both in terms of their optical elements and the electronics. This gives you a clear advantage over other systems of the same or similar design.

                          Years of warranty

                          With proper use of the system and annual maintenance, we guarantee protection against broken lamps for ten years from the date of installation. In addition, it is possible to extend the existing warranty (two years for the entire system including the optical elements) to up to four years. Contact us. We’d be happy to tell you about the details.
