Title: Vyacheslav N Matveev: Innovator in Arc Welding Technologies
Introduction
Vyacheslav N Matveev is a notable inventor based in Saint-Petersburg, Russia. He has made significant contributions to the field of welding technology, holding 2 patents that showcase his innovative approaches to arc welding.
Latest Patents
Matveev's latest patents include a "Method of Arc Welding" and a "Method of Multi-Pass Narrow Groove Arc Welding." The "Method of Arc Welding" involves a technique where the end of the consumable electrode is submerged into the molten pool. The maximum cross-sectional dimension of the electrode end is carefully chosen to not exceed twice the minimum dimension of this cross-section. This method ensures that the weld width is achieved by adopting a minimum dimension that is less than the required width but no less than half of it. The arc length is set below this minimum dimension, and the consumable electrode is fed at a speed lower than the welding speed, optimizing the welding process. The "Method of Multi-Pass Narrow Groove Arc Welding" focuses on welding heavy-gauge metal with narrow grooving. In this method, the initial electrode extension is adjusted to be greater than the depth of the grooving, allowing for precise control over the welding process.
