Mechanical joining of advanced steels (MECOFAST)
Important results from the project
The project has evaluated and validated three mechanical joining techniques (flow drill fastening, self-piercing riveting and plasma pin joining) for high-strength steels and multi-material combinations. The results show that the methods have great potential for joining high-strength steels, but with some limitations depending on the strength and thickness of the materials. Disassembly methods were also developed and tested, creating a vital foundation for circular material flows.
Expected long term effects
The project enables increased use of lightweight, strong materials in the vehicle industry, leading to reduced weight, lower emissions, and improved crashworthiness. By developing efficient disassembly processes, it enhances the potential for a circular economy with increased recycling and reuse of materials. This strengthens the competitiveness of Swedish industry through sustainable and resource-efficient product and production solutions.
Approach and implementation
The project was executed as planned in three work packages. WP1 focused on evaluating joining methods through experimental trials. WP2 investigated and tested disassembly and re-assembly methods to promote circularity. WP3 handled project management and dissemination of results. The collaboration between the research institute (RISE), an end-user, and technology suppliers worked excellently and was crucial for the project´s success. The timeline was followed.
