Welding
Achieve fine, precise spot, and seam welding for both metals and plastics with ACSYS laser systems.
ACSYS laser processing systems facilitate welding processes of the highest quality. Depending on the material for a given application, different processes are used, but ACSYS welding systems consistently achieve reliable and efficient results without the need for additional material. Thanks to the option of flexible power and pulse design, our systems also make it possible to create special effects along with custom pulse shapes and trains.
Valve connection in the mm range
Creating a fixed connection on a valve by welding a threaded head onto a micro valve. The shaft of the valve remains free of melt and does not warp.
Plastic welding of speedometer bezels
Contactless laser welding is used to join speedometer bezels precisely, reliably and durably. Joining different plastics and polymers without chemical adhesives is possible with laser technology.
Welding an electronic component
In the precision welding of electronic connections, modern fiber lasers enable particularly fast and efficient welding without the addition of materials such as crimp sleeves, flux or solder. Laser welding also enables particularly short process times with maximum precision. Another plus is the fact that the heat input into the material and the surrounding plastic is minimal, making it ideal for sensitive electrical components and sensors.
Metal Welding
If metal components need to be joined together inseparably without the addition of material, laser welding is the most ideal solution. This method also provides exceptional flexibility. With the innovative fiber laser technology from ACSYS, the spectrum ranges from the finest spot welds to meter-long deep-welded seams with slim geometries and minimal distortion. Thanks to the very effective focal depth of our lasers, process-tolerant welding is possible even with materials of different wall thicknesses or when the alignment is not perfectly perpendicular.
ACSYS laser processing systems are capable of both metal welding processes, heat conduction welding (melt or fusion welding), and deep penetration welding (keyhole welding).
Heat Conduction Welding
In heat conduction welding, the laser only melts the surface layer of the material. The materials flow into each other and then solidify, creating a durable and lasting connection. The process achieves welding depths of typically < 1 mm and is well-suited for joining thin-walled parts. The laser produces a smooth, rounded weld seam that requires no post-processing.
Deep Welding
During deep penetration welding, the laser beam creates a vapor capillary in the material, also known as a keyhole. This extends to approximately 1.5 times the diameter of the laser beam focus and is guided through the workpiece by the system’s movement control. The molten metal flows around the capillary and solidifies behind it, forming a deep, narrow weld seam with a uniform structure.
This process joins multiple layers of material at once and achieves high welding depths. It combines excellent efficiency and high welding speeds with a very small heat-affected zone, which protects the material and prevents warping.
Plastic welding
Laser welding of plastics is carried out using the overlap welding process and works on the principle of laser absorption welding. In this method, the two joining partners are placed on top of each other. The laser beam penetrates the upper joining partner, and the energy is absorbed by the lower joining partner, which heats up. The heat is then transferred back to the upper joining partner, forming a common fusion band. As the material cools, pressure is applied from the outside to create a high-quality welded joint.
For the best results, the materials used must be the same or compatible, and a component-specific optimized laser technology must be selected for welding. Our team is happy to advise you in selecting the right setup.
