WPS Qual on Inco 713

Date 02-13-2011 15:58

Hello everyone. I have a requirement to qualify a WPS for Inconel 625 to Inconel 713 using ER NiCrMo-3 filler, manual GTAW. I am not familiar with the 713 but from what information I have found, it appears to only be available in casting. I am looking for any information, tips, and/or experiences with this combination of materials.
Thanks
scott

Any Inco catalog will tell you that. If you havn't one at hand, ask Inco:

Here is a good link or two that will help you find what you're looking for:

Here is an interesting thread from another forum regarding the weldability of Inconel 713 FWIW...

It appears that the 713 is not as readily weldable as the 625 is, and as Professor Crisi suggests - contacting Special Metals via the second link shown above is probably the best course to follow in order to get the knowledge you need regarding your query.
