Commissioning and industrialization of a laser vacuum welding station for Endress+Hauser

Following the successful development and validation of the laser vacuum welding process on a laboratory scale, the next logical step was to transfer the technology to industrial series production. The aim was to transform the knowledge gained in the test environment into a robust, production-ready plant concept.

The project focused on the design, detailed planning, and construction of a laser vacuum welding station at the Reinach site (Switzerland). In addition to the technical design of the plant, this also included the structured implementation of quality approvals and targeted upgrading until the plant was fully production-ready. The goal was to make an innovative joining technology stable, reproducible, and economically viable under real industrial conditions.

The aim of the project was the consistent industrialization of the newly developed welding process and the provision of reliable quality assurance under real series production conditions. The focus was on transforming a technologically validated process into a stable, reproducible, and economically viable production solution.

To this end, the process-relevant parameters were systematically verified, quality criteria defined, and suitable testing and verification concepts implemented. Validation under series production conditions created a reliable data basis that provided lasting proof of both process stability and compliance with the required quality standards, thus ensuring the prerequisites for long-term series production.

The particular challenge lay in the fact that this was an innovative welding process and the first plant of its kind in the world. There was no technological blueprint available; instead, the task was to transform a highly sensitive process that had been tested on a laboratory scale into an industrial-scale, permanently stable series solution.

The focus was on reliably controlling the process-critical influencing factors and demonstrating consistently reproducible quality under real production conditions. At the same time, the scalability of the process had to be ensured and its technological maturity in an industrial environment gradually verified.

The combination of pioneering technology and demanding quality requirements necessitated close integration of process development, plant design, and production integration in order to achieve sustainable, robust, and economically viable series production.

The industrialization of the laser vacuum welding process was implemented successfully and on schedule. The planned quality acceptance confirmed stable mastery of the process and product requirements under series production conditions.

Production start-up was structured and led to regular series production without any significant deviations. This ensures long-term process reliability and economically viable production.
