Effects of the Welding Process on Mechanical Properties and Corrosion Resistance of 2205 Duplex Stainless Steel

摘要

In this study, welding of 2205 duplex stainless steel was carried out by first using plasma arc welding as root welding and then using tungsten inert-gas (TIG) welding and metal inert-gas (MIG) welding respectively as cover welding, Weldability of 2205 duplex stainless steel using two different the welding processes is investigated. Microstructure characteristics, mechanical properties, pitting corrosion resistance are made comparison between the weldment that is solution treated and that is not Influence of heat input and the solid solution treatment on complex properties of welded joints is evaluated, and the solid solution treatment was conducted for both of the welded joints fabricated by the welding processes mentioned preciously.
