摘要
使用ER316L、ER309L及ERNiCr-3焊丝对06Cr13换热钢管与06Cr19Ni10管板进行平缝GTAW管头自动焊接,通过PT、Leica显微镜和维氏硬度等方法检测,06Cr13换热钢管与06Cr19Ni10管板使用ER316L焊丝进行焊接时,焊缝没有裂纹,组织性能最优,说明试验所选焊接工艺参数是合理的,ERNiCr-3焊丝焊后试件存在裂纹,试验不合格。
ER316L,ER309L and ERNiCr-3 welding wires were respectively used in GTAW welding of 06Cr13 heat exchange tube and 06Cr19Ni10 tube sheet. Then the welding seams were tested by using PT, Leica microscope and Vickers hardness tester. The results show that, when using ER316L as wire material, the welding seam has no cracks ,and has the best weld organization.
