TruDiode

The energy-efficient diode laser

Cost-efficient welding expert

The extremely energy-efficient TruDiode diode lasers impress through optimal results and low operating costs. Whether for deep welding, heat conduction welding and laser metal deposition, soldering, or plastic welding: the lasers deliver excellent seam qualities with laser powers extending into the multi-kilowatt range. With its modular, space-saving design, you can integrate the TruDiode easily in your production systems. You can supply up to four work stations flexibly within the laser network.

100% consistent power output

Stable processes through integrated, active laser power control ensure reproducible results.

up to > 40% efficiency

The TruDiode saves resources with its high degree of efficiency and intelligent energy management.

Flexible in use

The welding expert joins plastics or metals, both with and without auxiliary materials.

Extremely compact

With its direct diode principle, the TruDiode impresses with a footprint that is considerably less than 11 ft2.

Always ready

Long service life through passively cooled diode modules

Energy-efficient structure of the TruDiode optics
Economic miracle

TruDiode lasers contain virtually no consumables. The intelligent cooling concept with integrated heat exchanger means that there is often no need for an external laser cooler. You can also cool optics and optical laser cables with the cooling water of the diodes. Together with the high energy efficiency of the TruDiode lasers, this leads to very low investment and operating costs.

Modular construction

The modular and space-saving design enables quick and simple integration of the TruDiode laser in your production system. It is also easy to upgrade your TruDiode later. This enables you to adapt the laser power or the number of outputs in the field if your requirements change.

Laser-soldered component
Multiple options for the material

The TruDiode diode lasers are well-suited for processing metals and plastics. With high beam quality and output powers from 150 to 6,000 W, you can count on perfect welding and soldering results.

Plastic welding with TruDiode

Plastic welding with TruDiode

The TruDiode diode lasers enable non-contact welding of thermoplastics by means of transmission welding. Here they achieve connections that are extremely strong, dense, and aesthetic. The transmission welding process enables virtually any welding geometry in the overlapping joint. The precise energy input results in minimal thermal and mechanical load.

Heat conduction-welded gastronomy containers

Heat conduction-welded gastronomy containers

In heat conduction welding, the TruDiode joins the mating parts along the seam point. The molten masses flow into one another and set to form a weld seam. This is smooth and rounded, and therefore, does not require rework. The procedure is used to join thin-walled parts, for example for corner seams on visible edges.

Bending tool hardened with TruDiode

Laser-hardened bending tool

The TruDiode is ideal for the laser hardening process. With low heat input, component distortion is low which reduces or eliminates the need for rework. The laser also enables the processing of irregular, three-dimensional workpieces.

<p>In laser metal deposition (LMD), the laser generates a weld pool on the component surface. Metal powder is automatically introduced through a nozzle. Beads form that are welded to one another, which then form structures on existing base bodies or entire components. Here, a screw conveyor has been applied layer by layer to a tube using LMD. In comparison to other generative processes, LMD has high build-up rates and therefore, a high process speed.</p>

Laser-soldered component

Soldering

Soldering with the laser produces an optimal join between the mating parts with the solder. The lower melting temperature of the filler material in comparison with the component material means that only the solder melts when the laser is used for processing. The solder flows into the joint gap and bonds with the surface of the workpiece (diffusion bonding).

With TRUMPF you have the option to adapt your solid-state laser with flexibility 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 supply several work stations at the same time. The TRUMPF Remote Service helps ensure your system remains available, anywhere and at any time.

Active power regulation of the TRUMPF solid-state lasers
Active laser power control

Regardless of the age of the laser device or the ambient conditions, the laser power is maintained at a specified value (with a typical deviation of ±1%). This ensures that the process results are reproduced across the entire service life of the laser.

Fixed optics that can be combined with the TruDiode
Cooling processing optics/optical laser cables

Processing optics and fiber optic cables can be cooled easily and conveniently using the laser cooling water. Separate cooling is therefore, not necessary.

TRUMPF Remote Service
Remote Services

In the event of malfunctions, TRUMPF service experts will remotely access your laser via a secure remote connection. In many cases the error can be remedied in this way, or the laser configuration can be modified to enable you to continue manufacturing until the spare part arrives. This enables maximum availability for you.

Variety of interfaces for the TRUMPF solid-state lasers
Interface variety – for simple integration

Interfaces are key for the integration of a TruDiode laser in your machine or production line. The solid-state lasers from TRUMPF offer interfaces to all common fieldbus systems. Also available: real-time interface, parallel digital I/O, interface for process sensor systems, OPC UA software interface, analog input card, interface for intelligent TRUMPF optics, e.g. CFO or PFO.

The TruFiber has an interface to connect TRUMPF processing optics, such as the PFO 20.
Intelligent down to the workpiece

The TruDiode has interfaces to control intelligent TRUMPF optics, such as monitored CFO focusing optics or PFO scanner optics. You can program the processing optics easily via the laser control system, and there is no need for an additional PC or control. Recorded data and associated limit values including warnings and error messages can be visualized in the TruControl laser control system.

Optical arrangement of the TruDiode
Flexible beam guidance

There are many different options for the beam guidance that will enable you to plan flexibly with your laser. The beam guidance is integrated into the compact housing. The plug & play optical laser cables can be easily connected to different work stations. You can choose the number of fiber outlets up to a total of two or four. The modular design means that the laser power and the number of outlets can be changed retrospectively in the field at any time.

TRUMPF laser network
TRUMPF laser network

With the laser network, you can connect one or more TruDiode lasers with up to two or four 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 increases the capacity utilization for the laser, reduces the part costs, and even enables you to combine different applications.

TruControl control

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 controls 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.

The TRUMPF sensor systems mean that your production will always be both effective and cost-efficient. The sensor products VisionLine, CalibrationLine or integrated pyrometers ensure stable processes by monitoring all the procedures in laser production and make a significant contribution towards your process reliability. Processing continues unimpeded 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 in the correct location.
