Technology Aims

The three key features QCOALA will focus on are:

Quality - A reliable in-line quality assurance for the QCOALA applications will be achieved. Fully integrated process ICT and Statistical Process Control (SPC) will facilitate in-line quality control and achieve higher throughput and yield, through reduction of scrap rates below 1% and reducing pseudo-errors below 1%. Beneficiaries expect the approach to increase yield by between 2 and 10%.

This project will help the Beneficiaries, with expertise in the constituent components of the new laser system, to increase their annual turnover between 15 and 25%, their productivity between 50% and 100% and their yield between 2 and 10%.

Productivity - By using the new laser system, with its dual wavelength capability, and tailored welding strategies developed for both thin-gauge aluminium and copper, the energy needed per weld will be much less compared with currently used manufacturing processes. In addition to the high weld quality achieved through in-line monitoring and inspection, the reliability and durability of the new approach will be superior to existing technologies. The qualities of samples of >100 pieces (existing technologies vs. QCOALA technology) will be evaluated by (non-destructive) inspection and compared to each other. Additionally, the energy consumption will be analysed. It is expected that the energy consumption will decrease by >20% per weld, with Beneficiaries estimating an increase in productivity of between 50 and 100% and a yield increase between 2 and 10%.

Autonomous operation - All system components will be integrated through robust ICT protocols to ensure that product quality can be assured and maintained (QA/QM), and full autonomy of the processing system. The introduction of 100% inspection through integrated process monitoring and in-line weld inspection will reduce scrap rate and repair costs of the high-volume automotive and alternative energy applications under investigation. However, this will only be economically acceptable, when this is carried out in-line, allowing remedial action to be taken immediately, through process-based ICT.

Interaction of technologies to be developed in QCOALA is shown below.
