Research project prepare today's welding processes for tomorrow's demands

The manufacturing industry worldwide has great demands on creating sustainable products and reducing its environmental impact. Requirements that force the industry to shift its production to new, efficient processes. For three years, the QWELD project coordinated by the University of Skövde will develop methods for quality assurance and optimization of laser and ultrasonically welded components.


Today, there are several different types of welding methods in the manufacturing industry. In the QWELD project, laser and ultrasonic welding are the focus. Techniques that are on the rise and that will be able to replace traditional welding. Laser and ultrasonic welding have greater safety and precision, they are also faster and use only a fraction of the energy required in traditional welding. Today, these welding methods are used, among other things, in the production of electric drivelines.

With the support of virtual technologies

What makes this project correlated with VF-KDO is that it will work with the virtual technologies and subject area PROCESS, to achieve project goal. For example QWELD will:

  • develop a multisensor-based system that will monitor welding quality in order to reduce manufacturing time. The system will be monitored in real time using machine learning.

  • develop digital twins of welding processes. By creating digital twins of processes, production can be optimized and costly physical stops can be avoided. The digital twins will be combined with the latest machine learning techniques to investigate how different parameters affect the weld. The aim is to reduce waste and create resource-efficient production.

Conversion to digital tools for increased competitiveness

The project will help the industry gain an increased understanding of the mechanisms behind welding and how manufacturing companies, by taking advantage of virtual technologies and machine learning, can influence the quality of laser and ultrasonically welded components. Knowledge that contributes to the digital transition, and a continued competitive industry.


Funded by Produktion2030

The project is funded by the innovation program Produktion2030, a joint venture by Vinnova, Formas and the Swedish Energy Agency.


The goal of the program "Produktion2030" is to increase the Swedish manufacturing industry's global competitiveness by building a sustainable and resilient manufacturing industry. With the Swedish national sustainability goal of becoming fossil-free by 2045, it is natural and crucial for universities, research institutes and companies to build interdisciplinary research groups to develop new and sustainable manufacturing techniques, for example for electric vehicles.
