Title: Nikolai A. Eroshkin: Innovator in Arc Welding Technology
Introduction
Nikolai A. Eroshkin is a notable inventor based in Saint-Petersburg, Russia. He has made significant contributions to the field of welding technology, particularly through his innovative methods that enhance the efficiency and effectiveness of welding processes.
Latest Patents
Eroshkin holds a patent for a "Method of multi-pass narrow groove arc welding." This method involves multi-pass arc welding with a consumable electrode in a protective atmosphere, specifically designed for welding heavy-gauge metal with narrow grooving. The invention includes adjusting the initial electrode extension to be greater than the depth of the grooving of the welded joint. Additionally, a current supply conductor that supports the consumable electrode is positioned above the welded joint, allowing for a decrease in the length of the electrode extension with each pass. The voltage applied to the current supply conductor, the rate of feed of the consumable electrode, and the welding speed are all reduced as the length of the electrode extension decreases.
