Automated scanner for kissing bond detection in friction stir welded materials
Friction Stir Welding (FSW) is a material joining technique that is a major breakthrough due to its substantial advantages compared to other techniques for welding aluminum alloys. This has allowed aircraft manufacturers such as Boeing to achieve 60% cost saving and reduce manufacturing time by 73% in aircraft models. This is only a fraction of what could be achieved. Despite its merits, FSW use is still limited due to a certain defect termed “kissing bond”. Kissing bonds reduce the stress-load resilience of FSW materials and are extremely difficult to detect. Thus, out of fear of low fatigue performance, aerospace and automotive manufacturers cannot leverage FSW to its full potential which translates to manufacturing cost savings of €1.6 billion, fuel savings of €1.9 billion and a reduction of 2 million tons of CO2, during the next 20 years. 

This gap gives rise to a unique business opportunity which Vermon (developer  of nonlinear ultrasonic transducers) and RISE (expert in signal processing algorithms), IKH (high-tech SME specializing in human-machine interfaces and service robotics) along with Coskunoz (leader in FSW machinery with commercial presence in 4 continents) seek to seize with the aid of TWI (world class research institute who originally invented FSW) by commercializing FrictionHarmonics. 

FrictionHarmonics is the fruit of four years of R&D financed by private funds and public grants. It has already been validated in a relevant environment and is proved to detect kissing bonds of less than 0.3mm in diameter with 100% accuracy. 

We now need to finalize the system’s commercial version, certify it, and validate its performance in a complete FSW production line. Our primary target customers will be aerospace and automotive manufacturers in Europe and North America. To this end, we request a grant of €2.2m. Our aim is to grow our businesses by €33.44m in gross cumulative revenue, operating at a profit of €13.83m and generating 215 new jobs over the 5 years after market launch.
