QuellTech laser metrology in practice
1. Compensation of thermal distortion during weldingAs during the process, considerable heat is supplied to the component, thermal expansion cannot be neglected, as the optimum welding position shifts. As a consequence, the mechanical strength of the connection after completion of the process may be insufficient. If not detected in time, major damages caused by rupture cannot be excluded.
QuellTech laser scanner prove to be extremely useful for these applications, as they are able to correct the position and thus the path immediately before the process is launched.
2. Weld Seam Inline InspectionBesides robot welding, welding guided on machine shafts still represents a usual procedure in industrial applications. Inspection normally does not take place before completion in a separate test routine. By integration of the quality supervision by a laser scanner directly at the end of the process, an additional test routine can be omitted.
This way it is possible to discover improper welding of a long seam (e.g. of a tank) without major delay, otherwise expensive rework would be inevitable. The same is valid for fine defects like cracks, pores or spatters. This prevents production of long passes requiring rework, or even scrap. The quality of the weld is documented at the same time.

3. Weld gap inspection with slag detectionA specialist machine manufacturer for welding systems was looking for a solution to improve weld seam control in a multi-layer welding process with slag detection in the deep gap. Previous offerings were limited, and unwanted reflections in the deep gap made the task more difficult. The customer also needed flexible software that he could customize and program himself. QuelleTech implemented two Q4 laser scanners before the welding process to illuminate the side walls and bottom of the deep gap. The reflections were minimized and the QuelleTech QS View basic software allowed the customer to flexibly adapt the software to their requirements. This enabled the customer to have better weld seam inspection and slag detection, which sets their welding systems apart from the competition and offers investment security.
Monitoring crimp connections is crucial for the quality and reliability of spindle drives in vehicles. Safe and durable connections are particularly important in electric tailgate systems, which are used in everything from luxury to compact cars.
We would be happy to carry out a first free of cost test measurement for you with your laser scanner applications, give you an assessment of the feasibility and provide you with technical and sales support in the further procedure.
