Joining Metals Without Melting: A Revolution in Fabrication. In our FSW facility, we move beyond conventional welding methods that rely on heat to melt metal. FSW is a sophisticated solid-state joining process where heat is generated purely from mechanical friction, and materials are joined without ever reaching their melting point.
The process is unique and precise: a special rotating tool presses and “stirs” two metal parts until they become plastic—similar to kneading dough—then fuses them back together into an incredibly strong and homogeneous joint. Because there is no melting, this method drastically reduces the risk of weld defects like porosity or cracking. Our FSW facility is at the forefront of research for joining difficult materials, such as high-strength aluminum alloys for aerospace and automotive applications, producing weld joints whose quality often exceeds the strength of the parent material itself.
