On July 25, 1984, the engineer and pilot Svetlana Savitskaya became the first woman to take a spacewalk, when she was at the Russian orbital station Saliut 7. During her extravehicular mission, which lasted 3 hours and 35 minutes, this Moscow-born cosmonaut carried out the first welds carried out in outer space, supported by his partner Vladimir Dzhanibekov.
To do this, he used a tool devised at the EO Paton Electric Welding Institute in Kiev, which had been working on this technology since 1969. That same year, the crew of the Russian Soyuz 6 ship had already experimented on board with consumable electrodes , an arc low pressure plasma and electron beams.
The Isparitel evaporator used by Savitskaya used precisely two high energy density electron beam guns.
