| Popis: | Ultra high strength steels UHSS are increasingly used in dynamic highly stressed constructions such as mobile crane booms to realise light weight designs with highest maximum loads. To guaranty sufficient mechanical-technological joint properties in welded joint, the monitoring and control of the cooling times is required. Hence, in this work, a challenging approach is the accurate in-situ and real-time sensing of the energy input in MAG laser hybrid welding of UHSS processed by sophisticated IR thermography sensors for robust “zero-defect manufacturing”. |
