摘要: 以冷轧态超级双相不锈钢S32750带卷，经成型后TIG焊接，制备规格φ50.8 × 0.89 mm的焊管。在不同的热输入量及退火温度下，制备焊管，采用万能拉伸试验机、金相显微镜、三氯化铁腐蚀试验，检测和分析力学性能、焊缝的形貌、宏观组织、耐腐蚀性能。最终确定焊接1.0 m/min，焊接电流105 A、电压10.5 V、退火温度1050℃情况下，焊管力学性能、焊缝组织、耐腐蚀性满足标准要求。
Abstract: The cold rolled super duplex stainless steel S32750 strip coils were formed and welded by TIG to produce φ50.8 × 0.89 mm welded tubes. Under different heat input and annealing temperature, the welded tube was prepared. Universal tensile testing machine, metallographic microscope and ferric chloride corrosion test were used to detect and analyze the mechanical properties, weld morphology, metallographic structure and corrosion resistance. Finally, the mechanical properties, weld microstructure and corrosion resistance of the welded pipe meet the requirements of the standard under the condition of welding current 105 A, voltage 10.5 V and annealing temperature 1050˚C with a welding speed of 1.0 m/min.
