HOW TO HANDLE HIGH LASER OUTPUTS WITH TOTAL PROCESS RELIABILITY
The High Power welding module with infrared (or, alternatively, green or blue) wavelength is an established piece of laser welding technology based on F-Theta lenses. With the High Power welding module, you, as a machine and plant manufacturer or integrator, are ideally positioned to meet customer requirements for very high laser power outputs with 100% process reliability. The High Power welding module with the digitally controlled SUPERSCAN IV-30 2-axis deflection unit can be quickly and easily integrated into new or existing machine and production lines.
The cost-efficient, modular laser welding application is ideally suited to industrial applications with a specified laser working field of up to 300 x 300 mm. These include, for example, welding of battery cell covers or tab welding, i.e. welding of cell contact surfaces made of aluminium or copper plates. The High Power welding module uses remote welding in combination with a robot. Deflection units with apertures of 20 to 30 mm ensure top-quality results during laser welding of metals and plastics.
Flexible wavelengths and materials
We strive, above all, to achieve usability, quality and productivity. That’s why all development, man- ufacturing and functional testing of high-quality laser applications for virtually all sectors happens exclusively in our own in-house laboratories and production facilities. We guarantee fast service and expert maintenance by means of our global support network.
The wealth of variants within the various component groups of our High Power welding module maximises your flexibility as a machine and plant manufacturer when planning, designing and (re)constructing diverse production lines. As an engineer, the diversity of options to choose from means that you’ll enjoy a greater scope of design and more freedom to realise your complex developments.
The High Power welding module guarantees the following for all standard fibers and laser wavelengths:
Innovative weldseam quality assurance is based on coaxial on-axis process monitoring, achieved by means of a high-power camera adapter for a camera, welding monitoring or a pyrometer.
In terms of software, the preconfigured control cards also enable fast, smooth integration of the High Power welding module into machines and systems, as well as into high-level systems if required. Preconfigured cards facilitate the customised definition of individual welding cycles.
This is done by the end customer before the start of the process using the mapped laser process in the software – much like a geometry in a CAD system. The plant operator sees the welding contour in the complete process field and can assign various parameters to it, such as laser power output or speed. For example, it is possible to specify that the laser power is to ramp up over a certain period at the start of a contour, distributed over several curve points. Over the course of the welding contour, the metal heats up and absorption increases. It is then possible to specify in the programming that the power should decrease linearly (e.g., by 5%) between two or more points. Finally, at the point where the end and the start of the welding contour meet, the process can be ended with a somewhat steeper downward slope.
A modulation in the laser beam in a spiral-shaped forward motion creates a homogeneous melt pool. With highly functional control cards, you as a machine manufacturer or integrator, will significantly reduce your programming costs, as the software development kit (SDK) makes it much easier to modify a client-side library.
Stable production times with a longer operating time are achieved in the High Power welding module thanks to an optional air knife, which improves optical cleanliness. Optional stainless steel components also offer protection from corrosion.
Guarantees fast and easy interactions for customised programming. User-friendly set-up and calibration of the deflection unit and effortless automation.
Can be used universally as well as specifically for indi-vidual requirements. The laser system can thus be op-timally controlled, optimised during development and monitored during operation.
