Investigation of the Pyrometallurgical, Physical and Mechanical Behavior of Weld Metal

Abstract

The physical and chemical behavior of welding consumables were investigated. The influence of strain and weld metal composition on weld metal microstructure, properties and cracking behavior were studied. Advanced concepts were evaluated to produce higher purity and more consistent welding consumables. New method to quantify welding consumables were studied. Four different research topical areas are addressed, but all are concerned with the pyrometallurgy and physical metallurgy of weld metal. These topical research areas are entitled the following: a. Steel weld metal phase transformation, b. Weld metal pore formation and methods to retard porosity, c. Advances in welding flux research, d. The hot cracking behavior of aluminum alloys.
