Laser spot welding with galvo scanner - high-precision spot welding at maximum process speed

Laser spot welding with galvo scanners is a state-of-the-art method for the precise joining of metallic materials. The laser beam is deflected by two fast-moving mirrors (galvanometers) and focussed precisely on the welding spot. The laser beam is moved without contact and at extremely high speed, making the process particularly efficient and low-wear.
In contrast to conventional laser welding systems with mechanical axis movement, the galvo scanner offers significantly higher dynamics and positioning speed. This is a decisive advantage, particularly in applications with many welding points - for example in electronics production, medical technology, sensor technology or battery cell welding.

The high precision of the Galvo system enables the smallest welding points to be set with exactly reproducible energy input. This means that even thin-walled or temperature-sensitive components can be joined reliably. In combination with pulsed or continuous fibre lasers, the heat-affected zone can be optimally controlled to prevent distortion or material damage. The process can also be easily automated and integrated into existing production lines. Quality assurance functions such as online weld seam monitoring and camera support can also be realised as an option.
