Abstract
A method of making a welded joint for constructions of maraging steels consists of making a Y-shaped grooving of edges with a shrink groove in a weld seam root. The junction is assembled by tack weld using a chromium-plated filling wire at a direct polarity current. The welding is carried out by multiple runs of argon-carbon dioxide gas-shielded welding.
