Slag-metal reactions during welding: Part I. Evaluation and reassessment of existing theories

Metallurgical Transactions B Aims and scope Submit manuscript

Abstract

A critical review of current thermodynamic theories of slag-metal reactions is presented. A series of preliminary experiments indicates that the previously proposed droplet theory is incorrect and the primary reactions controlling Mn, Si, and Cr content occur in the weld pool. In addition, these experiments show that the net transfer of oxygen is independent of the transfer of Mn and Si.
