The new technology produces a joint with good strength and is especially relevant for aircraft building.
As Interfax reports, scientists of the Institute of Theoretical and Applied Mechanics of the SB RAS (ITAM) mastered a technology for welding titanium alloy and aluminum. Previously such joints were considered extremely difficult.
According to ITAM scientific director Academician Vasily Fomin, the new method involves using a thin interlayer of magnesium or copper between the materials being welded.
In aircraft building such welding technologies may in future allow a shift from riveted joints to welded ones, which could substantially lighten airframe mass.
