| 摘 要： | 采用钨极氩弧焊（GTAW）和奥氏体不锈钢焊丝LNT309LSi作为填充金属，研究了Fe-Cr-2Al-Si阻尼合金和1Cr18Ni9Ti不锈钢的焊接工艺和焊接质量。借助金相显微镜分析了焊缝组织特征，采用电子探析分析了焊缝成分。按照国家标准研究了焊接接头的硬度、拉伸性能和弯曲性能。结果表明，用奥低不锈钢焊丝焊接Fe-Cr-2Al-Si阻尼合金和1Cr18Ni9Ti不锈钢，可获得理想的奥氏体＋少量的铁素体＋马氏体的焊缝组织，焊缝的抗拉强度和抗弯性能均高于阻尼合金。所采用的焊接方法、焊接工艺和焊丝能满足这两种钢的焊接要求，焊接质量可靠。

| Abstract: | The welding technology and quality of Fe Cr 2Al Si damping alloy and 1Cr18Ni9Ti steel have been investigated,with Tungsten Insert Gas Welding (TIG),and a high alloy austenitic stainless welding wire.The microstructure of welded joints was investigated by means of metalloscope.The major results obtained are as follows:an excellent weld structure with austenite,a little ferrite and martensite was obtained,the tensile strength and bend performance in the welded joint zone were higher than that in the damping alloy.The applied welding method,filler materials and weld process can satisfied the welding tequiraments of these two kind of materials.In addition,the quality of weld is reliable. |
