摘    要:通过钨极氩弧焊方法,对 1Cr18Ni9Ti 与 1Cr13 实施焊接.采用光学显微镜、扫描电镜对 1Cr13 马氏体型与 1Cr18Ni9Ti 奥氏体型不锈钢焊接接头进行金相组织、断口形貌观察及分析;利用显微硬度计、电子万能拉伸机测量焊接接头的力学性能;并通过海水模拟溶液浸泡试验,测量焊接接头极化曲线和交流阻抗谱.结果表明,通过手工钨极氩弧焊,采用直流正接接法,在合适的工艺下(焊接电流为 80 A,焊接速度为 110 mm/min),能够获得外观平整、组织均匀,力学性能与电化学性能符合要求的焊接接头.
Abstract:
The stainless steels of 1Cr18Ni9Ti and 1Cr13 were welded through deterministic craft by tungsten inert-gas (TIG) welding. The microstructure and fracture pattern of weld joints of 1Cr13martensite and 1Cr18Ni9Ti austenite stainless steels were observed and analyzed by means of LOM and SEM, the mechanical properties of the weld joints were measured with micro-hardness tester and electronic universal stretcher, and the polarization curves and AC impedance spectroscopy of weld joints were tested by seawater immersion test of simulation solution. The results show that adopting manual TIG welding through electrode negative to direct current soldering machine to weld 1Cr18Ni9Ti austenite stainless steel and 1Cr13 martensite stainless steel is feasible; under suitable process (welding current is 80 A, welding speed is 110 mm/min), weld joints can obtain good appearance and uniform structure; mechanical properties and galvano-chemistry properties can meet use requirements.
