efficiency when welding fillet welds TRUMPF is devoting special attention at this year’s Laser trade show to its own process sensors. To achieve a stable, rugged and reproducible process during laser welding, reliable sensor systems are a decisive factor. That is why TRUMPF has developed a variety of sensors and offers solutions for a wide variety of demands. By using appropriate sensor systems the tool, the workpiece position, and the process itself can be monitored and controlled precisely, right at the workpiece. These sensors, for example, lend stability to critical process parameters such as laser output and beam position and make corrections as needed. In addition, processing sensors can spot deviations from dimensional and position specifications and compensate for these. At the same time they can make projections on the quality of the welding seams. SeamLine Pro, a familiar and time-tested sensor system, helps the welding beam to meet the seam gap exactly. In the case of remote applications using a scanner, this task is assumed by a sensor system newly developed by TRUMPF. Here a high-speed camera, located almost coaxial to the laser beam, senses the seam and the position of the laser focus point simultaneously and adjusts the focusing optics so that the laser beam actually hits the seam. This new system is interesting especially

for the automotive industry, because increasing numbers of robots and programmable focusing optics are being used for fillet welds. The advantage of fillet welds is that they enable small flanges. This saves weight and material, increases energy efficiency, and reduces costs. To weld a fillet cleanly, the laser beam has to strike the seam very exactly, and this is exactly what the new sensors guarantee.
