Compared with the single phase stainless steel with high strength characteristics. In recent years, the rapidly expanding range of applications of duplex stainless steel, austenitic stainless steel has bee the most powerful petitor in many applications. This paper introduces the definition of duplex stainless steel, classification and performance as well as its internal organization and chemical position, and specific chemical constituents for each presentation. Then explained the choice for choosing different methods of duplex stainless steel welding, welding equipment, Finally in 2205 as an example focuses on the selection of welding parameters for welding materials, etc. to develop their research welding process.Keyword:Welding process。 Process parameters。 SMAW 目 錄摘要Abstract第1章 雙相不銹鋼1 雙相不銹鋼的定義和分類1 雙相不銹鋼的定義1 雙相不銹鋼的分類1 雙相不銹鋼的組織和性能1 雙相不銹鋼的基本組織特征1 雙相不銹鋼的基本性能1 雙相不銹鋼的化學(xué)成分2第2章 雙相不銹鋼的焊接44 雙相不銹鋼的焊接材料4 對焊縫金屬的要求4 焊接材料的選用5 雙相不銹鋼的焊接方法6 焊接方法的選擇6 雙相不銹鋼常用的焊接方法7 多層焊和工藝焊縫8 幾種雙相不銹鋼焊接接頭的性能8 雙相不銹鋼的焊接工藝要點9 雙相不銹鋼焊縫金屬的力學(xué)性能18
