Robotic welding of diverse products with the right partner

Tawesco is a manufacturing company based in Kopřivnice, in the northeast of the Czech Republic. With nearly a thousand employees, it is part of the family-owned PROMET GROUP. The company’s origins date back to the 1990s when it was spun off from the former state-owned company Tatra in Kopřivnice. Thanks to its specialisation in pressing and die production, Tawesco quickly established itself as a key supplier to the automotive industry.

First projects for segments other than the automotive industry

Over the years, it became clear that product variation was necessary for the company’s further development. The first projects in agricultural technology were realised in 2008, which were then welded entirely by hand. In 2017, a project followed that required the use of robotic welding. This project came about due to John Deere’s decision, a major supplier in agricultural and forestry technology, to outsource additional work. However, it turned out that even a “simple transfer” of existing technologies can be quite a challenge without the right partner.

Important project for forklift manufacturer

In 2018, Tawesco’s project team was challenged to produce components for forklifts for a major global player, Kion. After the experiences with the previous project at John Deere,
it was decided to find a suitable technological partner who could help automate the entire welding process.

Michal Raška, head of the investment department at Tawesco, says: “When looking for a suitable partner, we came across Valk Welding. After several meetings and discussions with Richard Mareš (senior technical advisor at Valk Welding), we concluded that gaining inspiration from companies that deal with these projects daily would only be beneficial. The technologies offered by Valk Welding, such as a functional system for eliminating inaccuracies in production preparation, advanced programming methods, and the general approach focused on the technology itself, appealed to us from the beginning. After a series of tests at Valk Welding’s demonstration centre, we were convinced that we were in the right place.”

The Tawesco team realised, after all previous experiences, that the requirements for robotic arc welding of large and heavy parts in small series differ from those for welding smaller components in mass production. The preparation and accuracy of production, the concept of welding jigs, and the programming of the robots require a specific approach that suits the nature of this production.

This marked the beginning of the long-term cooperation between Tawesco and Valk Welding in the field of MIG/MAG welding robotization.

Solutions suitable for projects of this type

In the following years, this cooperation deepened with further deliveries of robotic systems for new projects. The latest delivery from Valk Welding took place in 2024 in the form of two robotic systems, significantly reducing the production costs of previously manually welded parts once again.

Effective cooperation between companies

“The gradual development, the introduction of innovations, and the experiences gained with the operation of five robotic systems from Valk Welding have confirmed to us over the past seven years that robotic welding is also effective for small-scale production,” says Tawesco’s investment director, Mr. Martin Krupa. He adds: “Thanks to these modern technologies, we can also stably automate smaller series with the required high and consistent quality. This approach is an integral part of our vision - to be a respected family business that builds strong and long-term partnerships through innovations and complete solutions.”
