Hello everyone,
My company is reverse engineering a turbine engine component that consists of a small plate onto which two bolts are welded. The plate is most probably Inco 718, and I believe the bolts are Inco 718 or A286 (lab analysis pending).
My question is:
Are there separate specs governing post-weld heat treating, or are the normal heat treat specs commonly employed (i.e. AMS-H-6875 or AMS 2759/x).
Is it common to age the weld filler material to obtain maximum properties? Must you solution heat treat or anneal the weld first?
Anybody know a good spec or reference regarding welded assemblies of high temp alloys like Inco 718, Hastelloy, A286, etc.?
Thanks in advance for any assistance you can provide.
Regards,
Chris
