At just 16 years old, Jaël Krummenacher is European champion in full-contact karate and at the same time is completing her training as a physics lab technician at Axetris AG , a company of the Leister Group . In this interview, she explains how she balances training and work and what her next goals are. Jaël, congratulations on becoming European champion in full contact karate! How does it feel to hold such a prestigious title at the age of just 16? Thank you! It’s an unbelievable feeling, especially because of all the hard work and dedication that goes into it. Winning the title in May 2024 in the U18 heavyweight category in Istanbul was a big moment for me. It wasn’t easy, but it was definitely worth it. Can you tell us something about your path to this victory? How was the competition? The competition was tough. I had to deal with strong opponents, especially from countries like Latvia. Each fight lasts around two minutes and five judges assess every move. In the final, I competed against a Turkish karateka (a man or woman who practices karate) and was able to defeat her with the special technique “Ushiro do mawashi kaiten geri,” which I had practiced for a long time. It was a great experience and I was thrilled to take home the big trophy. It completes my collection of around 25 medals and awards. That’s impressive! How do you manage to combine your intensive training program with your training as a physics lab technician at Axetris? It takes good time management and a strong support system. I train four to five times a week, both in the dojo and at home. I have a personalized training plan that includes stretching, strength exercises and jogging once a week. My team at Axetris is very understanding and flexible, especially when I have to take time off for competitions. It’s definitely a challenge, but I enjoy both these aspects of my life and I’ve found a way to balance everything. Speaking of Axetris, you’re currently in your second year of training as a physics lab technician. What led you to take this career path? I have always had a love of math and science. Languages weren’t my thing. I came across Axetris at a job fair where I met a former trainee who had also done karate. I then decided to give it a try, and after a trial apprenticeship I knew it was the right choice for me. The work is fascinating and the company is very international, so I can learn a lot. What does a typical day at Axetris look like for you? My days vary quite a lot depending on the project. I conduct experiments in collaboration with other specialists and often help to build prototypes. Measurements and inspections in the area of gas laser detectors are part of our daily work. This involves performing tests to ensure that the products meet our quality standards. It’s a lot of precision work, and [...] => Interested in reading the rest of the interview or an apprenticeship at the Leister Group? Click on the link in the comments.

Learn how welding with 2-µm lasers unlocks new possibilities for joining transparent plastics. Discover more about the benefits of this technology and download our free expertise for detailed insights. Efficient Joining of Transparent Plastics with 2-µm Lasers: Laser transmission welding is a tried and trusted process for joining thermoplastics safely and precisely.

With recent updates in geomembrane welding standards focusing on precision, real-time monitoring, and improved quality control, the industry is moving toward more reliable and efficient outcomes. These changes reflect a growing need for greater accuracy and accountability in welding practices, which is crucial for industries that rely on durable, long-lasting geomembrane installations. The new ASTM D8580-24 sets clear guidelines for wedge welding of polymeric geomembranes, requiring machines to display and control key parameters like temperature, speed, and pressure. Meanwhile, ASTM D8468-23 focuses on data-driven quality assurance, emphasizing the importance of recording critical welding data for post-welding analysis. At Leister, our advanced welding systems are designed to align with these new standards. Our equipment allows for precise control over essential factors like temperature and pressure—key to ensuring consistent, high-quality welds. By incorporating real-time data monitoring and built-in data acquisition capabilities, we ensure every weld is meticulously documented, making it easier to meet these expectations.
