how to weld 2507 duplex stainless steel using AWS ER2594 and also using hastelloy G35?

[albaweld]

Looking for some tips in the process's applications for both GTAW (TIG) and GMAW (MIG) to this particular duplex on 1/8" plate....back purge pressures...cleanliness...speed...amps ...stringers as opposed to weaves...I would think that a weave would lead to lack of fusion because of fast freeze etc..best tools... contamination..etc.. heat and expansion co-efficients..any help or advice is greatly appreciated... thoriated tungsten?? Argon as opposed to helium??

Thank you, that is very helpful, Google is not broken, but over and above the information on line I was looking for a hands on approach also. Thanks again for taking some time out for this.
