| Résumé : |
High savings in welding time while maintaining or improving the quality of the welded joint - this was the driving force behind the development of a new optical setup at Evosys Laser GmbH. In the meantime, experience with a well-known German automotive supplier of two real components with increased safety requirements, for which extensive documentation had to be provided, has been gained. |
| Note de contenu : |
- Near-series tests on real assemblies
- Shorter cycle times with the same strength and more stable process
- Higher strengths with the same welding time
- Figure : A look into the production shows several radial welding machines shortly before delivery. The NGO technology is now abailable for all Evosys systems
- Fig. 1 : Damaged PBT assembly: since the transmission of the material is relatively low, there is a risk of superficial burns if sufficient laser power is used for laser welding
- Fig. 2 : Standard optics and NGO in comparison: welding time was significantly reduced for both components. The mean values of the measurements on five units are shown in each case
- Fig. 3 : Burst pressure comparison: the differences lie in the order of magnitude of the measuring tolerances
- Fig. 4 : Unchanged seam quality despite shorter welding time : standard optics compared to NGO. In the center of the image of the fractography of assembly I the fractured seam appears in the focus of the microscope. The images on the left show the view of the transparent joining partner, the images on the right the view of the absorbing joining partner
- Fig. 5 : Burst pressure comparison : mean values from five type I assemblies with the same welding time |
