摘　　要：SAF2205双相不锈钢焊接接头的力学性能和耐蚀性取决于接头能否保持适当的相比例。正确选用焊接材料、严格控制焊接热输入量以及制定合理的焊接工艺是双相不锈钢焊接的关键。进行了双相不锈钢的焊条电弧焊、手工钨极氩弧焊对接焊缝焊接工艺评定及产品的施焊,各项技术指标均满足要求,证明所选用的焊接方法、焊接材料、焊接工艺正确合理。They are used in many marine and petrochemical applications ,Due to its excellent corrosion resistance , it is used mainly for service in highly corrosive conditions or when a combination of very high mechanical strength and corrosion resistance is needed. It＇s the key to weld SAF 2205 that chosen welding materials,strictly controlled welding heat input and reasonable welding procedure parameters,The article gains a reasonable welding procedure and the matching welding materials are also determined on tube-to- tube-sheets wehting of Super Duplex Stainless.
