Both quality and productivity in the manufacturing of stainless steel tubes have a great potential for improvements by advanced processing by fiber lasers.
By innovative methodes like high speed video filming, theoretical analyses and generalized information management , the cut and weld process have been developed for different tube applications.
Laser hybrid welding, a combination of laser welding and MIG/MAG welding, has been evaluated for four different truck components. The long term goal is to replace MAG- and SAW processes to increase productivity. In this project, the new 15 kW laser at LTU was used. High speed video imaging and knowledge transfer from one application to another were challenging scientific methods. The project was done in co operation with Ferruform AB and is partly financed by Norrbottens Forskningsråd.
The main goal of the project is to improve the quality of teaching and training in production engineering through international cooperation and by innovative ICT-based e-learning methods like the CyberLab method.
In this project, simulation and testing of mechanical properties of laser hybrid weldshave been done for developing general joint design guidelines.
In this project a knowledge platform for lightweight construction with high strength steel has been developed. Particularly laser hybrid welding has been adressed.
In this project, process monitoring has been studied and developed by several industrial weld cases and high speed imaging of the dynamics of laser welding. Also simulation of process monitoring signals has been done.
