LASER WELDING

Precisely joining materials - laser welding offers unsurpassed flexibility

Laser welding is the ideal solution for joining different metals with high welding speed and low heat input, a small heat-affected zone and minimal distortion.

Scanner laser welding

Faster, more precise and more economical than conventional laser welding processes due to beam guidance via movable mirrors. Welding can be carried out dynamically in the processing field, thus eliminating non-productive time. Due to the design with a scan head, almost non-productive time-free processing is achieved at various processing points within the processing field.

Numerous advantages besides the high flexibility speak for the use of this modern concept. Any strength-related welding pattern can be applied to the components to be welded without additional movement of the workpiece or the welding head.

The combination of the laser beam with a high-performance deflection unit therefore represents the ideal combination for achieving optimum welding results. The following processing options can be carried out with the scanner welding process:

Heat conduction welding

The process is similar to spot welding. This welding process differs from spot welding in that the laser beam can be moved after the molten metal has been produced. The welding depth is usually less than 2 mm, which is why this joining method is mainly used for thin metals.

Laser spot welding

A process in which a laser is used to create a single spot weld to join metals. By focusing the laser beam, the light is absorbed by the workpiece and the metal begins to melt. The liquefied metal then solidifies, creating a spot weld. This process takes only a few milliseconds. Depending on the thickness of the material and the desired joint strength, further welding spots are set.

The welding laser system SG200 Weld offers an easy introduction to laser welding. You can process small and medium-sized workpieces in a cost-effective and space-saving way. The SG200 Weld laser system takes up about one and a half m² plus the mandatory, special laser smoke extraction. In combination with the programmable scanner unit, the SG200 Weld is ideally suited for scanner welding of various materials. The highest precision is guaranteed by the DPW (Dynamic Precision Welding) System. A camera in the beam path of the laser (on-axis) records the process zone via the mirror deflection of the scanner and thus enables precise positioning without distortions.

In addition, depending on the application, automatic position correction of the weld seam is possible in order to ensure process-reliable laser welding even for medium to large quantities.

In addition to reliable welded joints of metal, a wide variety of materials can also be welded
