摘要
对AP1000乏燃料水池采用的双相不锈钢ASTMA240UNSS32101的焊接工艺进行研究分析,分别采用焊条电弧焊(SMAW),药芯焊丝气保焊(FCAW)及熔化极气保焊(GMAW),进行相应的焊接工艺评定工作,对比不同焊接方法的焊缝力学性能,生产效率,焊接质量,生产成本,选出适用于生产施工的最佳焊接工艺。
the welding process of duplex stainless steel ASTM A240 UNS S32101 used in AP1000 spent fuel pool is studied and analyzed.(SMAW),flux cored wire gas shielded welding (FCAW) and melting electrode gas shielded welding (FCAW) are used respectively.The corresponding welding process evaluation work is carried out,and the welding mechanical properties,production efficiency,welding quality and production cost of different welding methods are compared,and the best welding technology suitable for production and construction is selected.
