2205 dual phase stainless steel owns the advantages of Auster stainless steel and Ferrite stainless steel and presents good apprehensive properties. Meanwhile problem in the weld process is the affect on the HAZ structure and properties from heat cycle.

• 2205双相不锈钢(DSS)综合了奥氏体不锈钢和铁素体不锈钢的优点,具有良好的综合性能,然而在焊接过程中最为突出的问题是热循环对热影响区(HAZ)组织和性能的影响。
