Procedure for Hardening Weld Metal during Its Formation

Abstract

A procedure was developed for controlling the process of crystallization of metal in the molten pool. This procedure insures intensive influence, regulated within wide ranges, on the pool metal from the reverse side of weld, without direct contact with the latter. Structural analysis and mechanical tests showed that performing electromagnetic treatment during welding makes it possible to considerably refine the weld metal structure.
