Scope
In the industrial sector, lightening structures is crucial for improving performance and energy efficiency. Combining aluminum and steel in bimetallic structures offers an effective solution by leveraging the properties of each material to reduce weight and enhance durability.
Welding these materials presents significant technical challenges due to their differing physical and thermal properties. The development of advanced processes such as FSW is essential to overcome these difficulties and achieve high-quality joints.
The project's goal is to optimize the lightening of structures through the welding of aluminum and steel components. It aims to design and manufacture structures using bimetallic materials with advanced welding techniques, such as explosion welding, arc welding, and Friction Stir Welding (FSW).
Solution
LORTEK focuses on developing and refining the FSW process, including the design of tools and the definition of critical parameters, to improve efficiency and quality in joining dissimilar materials.
- Design of structures for fabrication using bimetallic materials with explosion welding, arc welding, and FSW.
- Development of the FSW welding process, including FSW tools, process parameters, etc.
LORTEK contributes its expertise in developing these processes in collaboration with CAF R&D, achieving significant advancements in welding technology: Co-patent publication 'METHOD FOR WELDING TOGETHER DISSIMILAR PARTS' (EP 3 178 600 A1).
