Hanover Center of Excellence

For more than 70 years, our Center of Excellence has been in Hanover, Germany. In 2024, our Group opened a brand-new facility with new capabilities to support our growth. 

A symbol of our ambition to become a pure player in the electricity industry, our Hanover site brings approximately 70 experts (engineers, researchers and technicians) together to work on the electrical technology of the future. The new site has a footprint of 12000 m² and work around the clock for engineering and manufacturing Welding Machines, Cryogenics transfer lines and Superconducting cables.

Innovation, a priority

Hanover Center of Excellence includes in-house engineering and manufacturing of the most advanced technologies when it comes to the energy transition.

• Our Welding Machines serve the HVAC and HVDC Subsea cables, connecting offshore wind farms to the land for exporting the electricity generated by the wind turbines.
• Our Cryogenics joint-free transfer lines enable the safe and reliable transfer of cryogenics fluids such as the LN2 and LH2.
• Our Superconducting cables guarantees an efficient transfer of high power with minimal electrical losses and footprint.

With this combined expertise and our pioneering spirit, we are focused on the future of sustainability and electrification.

Together we are shaping the future of energy transmission and setting new standards for innovation and sustainability.

Thanks to the knowledge and understanding of its employees and its global innovation network, Hanover Center of Excellence will research solutions to increase energy output, improve the reliability, resilience and security of the grid, accelerate installation projects, and guarantee competitiveness and access to electricity by developing interconnections between countries, for example. All these innovations are focused on reducing the impact on the environment, notably through the use of new materials, more efficient technologies reducing CO2 emissions for our customers.
 

Main applications covered by UniWEMA® solutions

Our expertise extends across diverse sectors.

Our UniWEMA® Machines Business Line includes a world leading know-how in forming and welding in various market sectors such as Power and Optical cables, HVAC and healthcare: our forming and welding solutions enable the production of tubes and tailor-made products in a diameter range between 2 and 300 mm.

Our technology and solutions are a core element in our customers industrial manufacturing processes for the electrification and digitization, heating and cooling of medical supply sectors, to name a few.

# Welding technology

With more than 70 years' experience, we combine a wide range of magnetic and non-magnetic metals, noble metals such as platinum, alloys and surfaces - whether coated or highly reflective. We offer a full range of welding capabilities, from longitudinal and transverse techniques to circular welding, facilitated by robotic integration.

# Laser technology

We are the first to implement a green laser welding unit into a continuous welding process. Up to 50 % more energy is absorbed by copper in the green wave length spectrum compared to the infrared spectrum. We utilize this advantage to produce much smaller tubes with reduced wall thicknesses, still achieving the high seam quality that our customers have been used to from laser welding before.
