摘要：

In this study, Inconel 625 coating was deposited on the surface of A517 quenched and tempered low-alloy A517 steel using gas tungsten arc welding (GTAW) in order to increase the service life of the A517 substrate. For this purpose, Inconel 625 coating was deposited on steel surface by applying ERNiCrMo3 filler at different welding currents of 80, 100 and 120 A. The results showed that the microstructure of Inconel 625 coating consisted of a fully austenitic phase which was solidified having dendritic morphology, while A517 was found to be tempered martensitic. The average hardness of Inconel 625 coatings deposited at different welding currents was more than 230 HV. Evaluation of corrosion behavior also illustrated a better corrosion resistance of Inconel 625 coating than A517 base metal. The corrosion rate of Inconel 625 coating in 80 A, 100 A and 120 A samples was 0.435, 0.143 and 0.165 mpy, respectively, which were negligible in comparison with that of A517 steel (24.2 mpy).

[8] Q: We fabricate a lot of carbon steel pipes. Occasionally we get a job that uses carbon steel pipes lined with stainless steel. Sometimes the liner is 304L, sometimes 316L. Since the pipes have a relatively small diameter, they can only be welded from the outside. In preparing the joint, we peel back the carbon steel to expose the stainless in the root area, then weld the root and one or two more layers with gas tungsten arc welding (GTAW) using 309L (for a 304L liner) or 309LMo (for a 316L liner) filler metal, and argon backing gas. We finish the joint with 309L or 309LMo covered electrodes or flux core. This seems like a waste of expensive filler metal. After we get the stainless steel root pass in place, why not finish with carbon steel filler metal?
