Hybond AS has developed a new and revolutionary method for joining aluminium, called “cold welding”. The problem is that when two aluminium plates are welded using conventional methods, the strength of the material is halved. Hybond’s new technology maintains the material’s strength.
The technique also reduces material consumption, and consequently the weight of structures, such as housing modules for oil platforms, as well as ships, trains and planes.
The method is patented, and the market potential is considered to be virtually infinite. Hybond AS is a spin-off company from NTNU Technology Transfer.
