Practical tools — by practitioners, for practitioners

Knowledge is the only resource that increases when you share it. We have a rich treasury of knowledge and experience in laser application technology from the past two decades, and we’re not keeping it to ourselves.

Instead, it forms the basis for targeted development of our own laser welding technology products.

The starting point for our products is our own practical experience, combined with the drive to keep on optimizing processes.

Many of our own developments are now taken for granted in the everyday work of laser welding professionals. The positive feedback spurs us on to develop practical tools for the future — by practitioners, for practitioners.

A good example of this approach is our VDM 330 planar turntable — a turntable for laser welding components that are too large for a “normal” axis. hanks to this simple tool, precise positioning is possible. Our RoBo-1 roller block is used when round components need to be supported because they’re too long.

Our LAfet®-SM and LAfet®-SM Duplex wire feed systems and the mobile version LAfet®-SM Mobil contribute to process safety while decreasing welding time and therefore increasing efficiency.

Our own QUALAS® brand stands for the highest-quality welding fillers. They were developed in collaboration with experienced metallurgists and users. The portfolio is completed with a magnetic holding sphere that makes it easier to fasten workpieces optimally into work position during laser welding, polishing and mounting.
