LORTEK Democratizes Welding

DEVELOPS A ROBOTIC WELDING SOLUTION TO WORK DIRECTLY ON THE ACTUAL GEOMETRY OF THE PART

Automating welding remains one of the major challenges in the metalworking industry, where the actual geometry of parts often deviates from the theoretical model. To address this challenge, Lortek has developed a robotic welding solution capable of working directly on the real geometry of the part, eliminating the need for a prior CAD model.

With this project, the technology center takes a step forward in the democratization of flexible automation, bringing advanced robotic welding technologies within reach of a wider range of industrial companies.

Unlike conventional seam-tracking systems, which start from a nominal trajectory and perform local real-time corrections based on the average joint profile, Lortek’s approach introduces a paradigm shift. Instead of adjusting an existing trajectory, the system scans the real scene, automatically interprets the geometry, identifies joints or cavities, and autonomously generates the welding paths.

Greater scope
This new approach makes it possible to process single or highly variable parts, even when the CAD model is incomplete or entirely unavailable, significantly expanding the scope of robotic automation.

The workflow is structured in three stages: an initial scan using a profilometer or 3D scanner to capture the real geometry; a processing stage in which the software identifies the areas to be welded or filled and generates optimized trajectories; and process execution, where parameters such as travel speed adapt to the local geometry.
