Analysis of Existing Methods for Controlling the Structure of the Weld Metal
Abstract
Modern approaches to the management structure of the weld metal produced by arc, laser and electron beam welding. Analyzed various methods of modifying metal, including application of a mechanical treatment prior to welding, the introduction into the melt of various modifying additives, the implementation of an external periodic feedback and a repetitively pulsed heat input. The advantages of using pulsed-arc welding, providing a controlled heat input and control over micrometallurgical processes at intervals of formation and initial crystallization of the metal.
