Study of Solid state Phase Transformation in Duplex Stainless Steel Weld Metal by using Induction End heating technique

Abstract

Solid state phase transformation of duplex stainless steel weld metal was studied by induction heat source. Homogenous weld metal Duplex Stainless Steel 2209 was papered by physical simulation of weld metal and machined into cylindrical shape. One end of the specimen was fixed near induction coil resulting in highest heating from induction heat and decreasing toward another end. Different in temperature between both ends resulted in various solid state phase transformation as a function of temperature and distance. This methodology was conducted on physical simulation of weld metal in which it’s more economical than conventional study on an actual weld.
