A NEW MIXED-INTEGRATED APPROACH TO CONTROL AND IMPROVED WELDED QUALITY OR SURFACING LAYER PROPERTY IN THREE GAS SHIELD ARC WELDING PROCESSES

摘要

This article introduces three new electromagnetic field control welding and the surface welding technique, namely the gas shield metal arc surfacing technique with electromagnetic stirring and electromagnetic treating (EMS-EMT), the gas shield arc welding technique with dual-frequency electromagnetic field controlling (DF-EMS), and the electromagnetic stirring electrogas arc welding technique (EMS-EGW). The principles and characteristics of three welding processes are explained. The engineering application, basic research direction and development of these welding techniques are pointed out and discussed in this article.
