- Dissimilar Materials
- High-strength joint
- Optimised structural design
Welding of dissimilar materials is the key technology to improve productivity and quality in different fields including:
- Transportation: reduction of vehicle weight, and hence gas emissions, by joining light alloys with high strength joints (e.g. aluminium alloys to steel)
- Energy production: joining steels difficult to weld
The welding technology proposed by the UCL meets the market demand for joining with high-strength joints dissimilar materials that are traditionally difficult to weld.
The UCLouvain invention
UCLouvain has patented (developed) a friction based welding process called friction melt bonding that ensures obtaining a high-strength joint between dissimilar materials, even for dissimilar materials that are traditionally difficult to join (such as steel and aluminum). This high-strength joint avoids premature cracking. The production rate can reach a weld of 1 meter long produced in less than 2 minutes.
This work is the subject of one patent application:
