Використання екзотермічних процесів для відновлення пошкоджень у закритих порожнинах деталей машин та металоконструкцій

Abstract

The parts with holes such as hollow metal cylinders, flanges, sleeves and other are widely used in machine building and transport. Nowadays there are many ways of defects’ elimination that are formed on the external surfaces of such parts during exploitation. The problem is their elimination from the internal hard surfaces. The new method of recondition of such defects to exemplify drawbolt tram’s joist namely clefts’ welding that are formed on the inside surface of drawbolt by special exothermic method.
