Purpose and goal
Investigate the possibility to use hybrid welding .Further development of weld quality system for hybrid welding. Increase the knowledge of local geometry, residual stresses and defects. Design and development of demonstrators manufactured with hybrid methods. Further development of the technology platform LOST for knowledge and education within Swedish universities. The project results will be used and further developed within several production units within Volvo CE and its suppliers and contribute to education within KTH, CTH and HV.
Results and expected effects
The weld process control the fatigue properties, process development and process control are key factors for the usage of high strength material. Within the project different production conditions for manufacturing of more effective welded products which sustain severe operation conditions are studied. Furthermore after treatment is reduced.
Approach and implementation
Measurement systems analysis and tests with plasma hybrid welding is performed and analysed. Mapping of the occurrence of weld gap has been conducted. Studies regarding implementation of control chart, control diagram and quality strategies has been started. A study to correlate the ISO-standard (ISO 9013) for cut edges with fatigue strength is performed.
