摘　　要：SAF2205双相不锈钢广泛应用于石油化工行业裂解炉炉管。本文采用钨极氩弧焊打底+焊条电弧焊填充和盖面的焊接方法,选用合适的焊接材料和工艺参数进行焊接试验,并对焊接接头的金相组织、力学性能、抗晶间腐蚀性能进行了分析。结果表明,焊接接头的力学性能符合要求,抗晶间腐蚀性能良好。SAF2205 duplex stainless steel was widely applied in cracking furnace tube of petroleum and chemical industry. By using TIG welding primer plus arc welding filler and cap, selecting suitable welding material and process parameters,the microstructure, mechanical properties and resistance to intercrystalline corrosion resistance of the welded joints was analyzed. The results show that the mechanical properties of the welded joint conform to the requirements and the intergranular corrosion resistance is good.
