Human-machine collaboration driving performance
Our mission is to foster human-machine collaboration by offering operators a range of collaborative robots. Our goal is to eliminate the risky, tiring and repetitive aspects of their work. Operators benefit from improved comfort, produce higher-quality welds and cuts, and increase their productivity. At a time when many companies struggle to recruit, our collaborative robots make these trades more attractive.
Our story
Some inventions are born in a garage or at school — WeezBot came to life during a coffee machine break between Benoit Tavernier and Yves Guillermit. They shared their observations on the advantages and drawbacks of traditional robotics, which is highly effective for repeating operations in large series, but too cumbersome to implement for small batches or when the parts to be welded have dimensional variations. After reflection and discussion, the two engineers embarked on the venture with one idea in mind: to create a welding cobot that is easy to deploy and allows real-time process adjustment when needed. The name Weez-U Welding (“with you” and “welding” in English) was created to express our close support of welders in their work through better human-machine collaboration.
Drawing on their experience and expertise in industry, the two founders worked alongside field welders to create a solution that best meets their needs. The team grew, and several partnerships were established, notably with CETIM. The first WeezBot guided welding cobot was commissioned in 2022 and immediately demonstrated its flexibility, appeal and performance. The satisfaction expressed by our customers, together with our regular presence at trade shows, has helped raise awareness of this technology, which is attracting growing interest from welding industry players.
In 2025, the team numbers 12 people, ensuring the maintenance of collaborative robots in service and the continuation of technical developments requested by our customers. The company is well established in the French industrial landscape.
The values of
WEEZ-U WELDING
In our vision, technology serves people — not the other way around. The operator is at the heart of our project; they are the only ones capable of mastering the welding or cutting of a complex part. The goal is to make human-machine collaboration as effective as possible.
SAFETY: it is our top priority. Collaboration between people and our solutions is risk-free.
RELIABILITY: developed by our team of trusted professionals, our solutions implement reliable and robust technologies.
ERGONOMICS: we pay particular attention to the comfort and simplicity of use of our solutions to guarantee our customers a quick and effective onboarding from the moment of installation.
COMMITMENT: we keep our promises every day in order to satisfy our customers and honour our social responsibilities.
