About this document
Welding Practices for Duplex Stainless Steel by Tran Thanh Hao is a document available to read on EtoBox.
This presentation summarizes key information about welding duplex stainless steels, including Sandvik SAF 2304, SAF 2205, and SAF 2507. It discusses their metallurgical properties, recommended welding processes and parameters, filler metals, and measures to control ferrite content and hydrogen pickup. Maintaining proper heat input, interpass temperature below 250°C for SAF 2304 and SAF 2205 or below 150°C for SAF 2507 is emphasized, as is using shielding gas with 1-2% nitrogen for TIG welding to control fer
