CONTROL OF FORMATION OF WELDED JOINTS IN ESW (Review)

Abstract
Some technological approaches and methods for affecting the process of electroslag welding (ESW), aimed at optimisation of structure of the weld and HAZ metals, are considered. It is shown that the external magnetic fields providing the force effect on the weld pool by a contactless method are an efficient tool to control solidification of metal in ESW. The most effective schemes of electromagnetic control of the ESW process, ensuring homogenisation and refining of structure of the weld metal, are studied.
