Impulse friction stir welding uses mechanically produced time-dependent additional impulses of the tool and/or workpiece to deform and/or seal and solidify the material in the region of welding seam

摘要

Impulse friction stir welding uses mechanically produced time-dependent additional impulses of the tool and/or workpiece to deform and/or seal and solidify the material in the region of welding seam. Preferred Features: The additional impulses occur in one plane or several planes, straight and/or circular, with the same or different nominal value, phases, frequencies and amplitudes.
