    Sophisticated power pack

    The tried-and-tested pulsed solid-state lasers in the TruPulse series enable short, high-energy pulses at high power. The pulse power of several kilowatts for a few milliseconds means that spot welding and seam welding are now also possible in places where other methods fail. Thermally sensitive applications in particular benefit from the advantages of pulsed solid-state lasers. Thanks to their modular design, the lasers can be flexibly adapted to your individual manufacturing task. The TruPulse series has been technically optimised over decades, making the system highly reliable as a result.

    Flexible

    Individually adaptable lasers due to the broad product portfolio and the modular design of the TruPulse

    100% consistent power output

    The real time laser power control means that exactly the power you select arrives at the workpiece.

    Accurate pulse-to-pulse stability

    The laser compares the pulse shape you have chosen with the actual pulse shape in a 10 μs cycle.

    Improved average power

    With the burst function you can temporarily increase the average power several times over.

    Integrated expertise

    The WeldAssist option provides suggestions for all of the process parameters depending on the material and welding depth.

    TruPulse integrated beam guidance

    Thanks to its integrated beam guidance, the TruPulse can be perfectly adapted to your application. With up to six pluggable laser outlets and a flexibly configurable beam distribution, the laser beam can be split, switched over, disabled and measured. This makes it possible to use the solid-state laser at one or more processing stations, optionally with a time or energy split. This enables multiple welding processes to be performed in parallel or at staggered times. The modular layout enables subsequent repairs or upgrades in the field.

    TruPulse laser precision welding
    Finely graduated

    In terms of power, energy or focusability, the TruPulse series covers the full spectrum of parameters for laser precision welding. The parameters for pulse energy and pulse duration are variable – so the laser device can be designed precisely for your application and used flexibly during operation. With a maximum pulse power of up to 10 kW, pulse durations ranging from 0.2 to 50 ms and pulse energy of up to 120 J, the TruPulse lasers are perfect for many applications – both for manual working and for automated tasks.

    Burst function of the TruPulse
    Burst function

    The pulse energy and average power normally limit the pulse frequency of a laser. At the same pulse energy level, the burst function enables the frequency and therefore also the average power to be significantly increased for a short period. You can therefore minimise the welding time per processing cycle and increase your productivity.

    Endoscopic instrument

    High precision is vital for medical instruments. The TruPulse is perfectly suited to these applications. The welding seams on this endoscope are barely visible.

    Spot welding on electronic plugs

    Electronic plug

    Electronic plug contacts are often reshaped and then fixed in place with the laser. The reliability of the TruPulse lasers ensures highly productive 3-shift operation with reject rates of less than a percent.

    Seam welding on a sensor

    Sensor module

    The low heat input resulting from the pulsed laser process protects the sensitive electronics of the power sensor module, which was seam welded with the TruPulse.

    Laser welding a plug with the help of burst mode

    Plug

    With the aid of the burst mode function, the processing time for welding the plug is reduced by 70%. This is implemented by means of fast beam positioning via PFO scanner optics, paired with the capability of the TruPulse laser to emit multi-kW pulses with an increased frequency for short bursts.

    With TRUMPF you have the option to flexibly adapt your solid-state laser to your installation and operating situation. This applies, for example, to all beam guidance components and the control. You also have several options for the cooling water supply. Interfaces for different optics are provided right from the start. To save costs, your beam source can also supply several work stations at the same time. The TRUMPF Remote Service helps you to ensure your systems remain available, anywhere and at any time.

    Modular system of optical components
    Flexible, integrated beam guidance elements

    There are many options available to you for adapting the laser flexibly to your individual situation. In addition to the laser power and pulse energy, you can also choose the number of fibre outlets up to a total of six. The laser power is regulated for each outlet. The plug & play optical laser cables can be easily connected to different work stations. This allows multiple work stations to operate simultaneously with split laser power or one after the other with full laser power. The modular design enables field repairs to be carried out on site, as well as making the system suitable for retrofitting.

    TRUMPF laser network

    With the laser network, you can network one or more lasers with up to six work stations in each case. In the process, your laser either splits its power to multiple stations, or it supplies them by turns with full power. This allows you to even combine different applications such as welding and cutting with each other. The overall availability of your manufacturing systems therefore increases thanks to simple redundancy concepts.

    Convenient and flexible control

    The TruPulse can be equipped with virtually all standard fieldbus interfaces for control and actuation. The following are also available: real-time interface, parallel digital I/O, interface for process sensor systems, OPC UA software interface and analog input boards.

    The TruPulse features an interface for connecting TRUMPF processing optics, such as the PFO 20.
    Interface for intelligent optics

    Intelligent optics can be synchronised with your laser via a dedicated interface. This will allow you, for example, to use the CFO focusing optics or PFO scanner optics optimally for your purposes. You can program the processing optics easily using the laser control system. You do not need any additional PCs or control systems.

    Remote Services

    In the event of a fault, TRUMPF service experts will remotely access your laser via a secure remote connection. In many cases faults can be remedied directly in this way, or the configuration of the laser can be modified in a way that enables you to continue producing until the spare part arrives. This reduces production downtime.

    Flexible cooling options

    To cool the laser you can choose between water/water or water/air compressor cooling, which means that the TruPulse laser can also be used at high ambient temperatures. If you already have your own cooling circuit in place, you can use it in conjunction with a plate heat exchanger.

    WeldAssist

    The WeldAssist database provides you with welding parameters for various materials and focal diameters. The simplifies the set up of frequently changing laser applications.

    Intuitive operation thanks to TruControl

    TruControl

    TruControl is the control software for your TRUMPF solid-state laser – for quick and simple operation. You can program pulse shapes individually to match your application. The laser power is controlled in real time to ensure maximum reproducibility of your process results. In order to retrace important quality data of your produced parts even years later, the optional DataStore software module records all data relevant to quality.

    If external control systems are present, TruControl will communicate with them via all standard interfaces. Inputs are made via the touchscreen of the operating panel or via a panel PC. You can integrate your laser into the network via Ethernet and connect multiple PCs.

    Thanks to the TRUMPF sensor system, your production will always be both effective and cost-effective. The sensor products VisionLine, CalibrationLine or integrated pyrometers ensure stable processes by monitoring all the procedures in laser production, thus making a key contribution to your process reliability. Processing continues uninterrupted during the measurement – no interruptions are required, saving you valuable production time.

    Image processing

    TRUMPF VisionLine image processing detects features on the components and ensures that welding is always performed in the correct location.
