中文摘要：分别采用焊条电弧焊(SMAW)和钨极氩弧焊(GTAW)方法对SAF2205双相不锈钢管进行对接焊，并对其焊接接头的微观组织进行了观察分析, 对接头的力学性能进行了测试。结果表明, GTAW 焊接接头中奥氏体相含量较SMAW多，其综合力学性能较SMAW更好。
英文摘要： 2205 duplex stainless steel tube was welded by metal arc welding (SMAW) and gas tungsten arc welding (GTAW). The microstructure and mechamcal properties of the welded joint were analyzed. The results show that austenite phase in GTAW welded joint is more than that in SMAW welded joint. The comprehensive mechanical properties of GTAW joint are better than that of SMAW joint
