Does anyone know what welding wire should be used for argon arc welding of nickel alloys?

Does anyone know what wires are used for argon arc welding of pure nickel alloys Hastelloy B, Hastelloy B-2, Hastelloy C, and Hastelloy C-276? What welding process parameters should be chosen? Thank you!
According to the standard, choose a welding wire that is similar to the base material. GB/T 15620-1995 Nickel and nickel alloy welding wire http://bbs.hcbbs.com/viewthread.php?tid=325119&extra=page%3D1&frombbs=1
The simplest method is to cut a strip on the base metal and use it as a welding wire during TIG welding.
Thank you for your above replies. What issues should be paid attention to in the nickel alloy welding process? Our company's existing nickel alloy castings often require repair welding, and the process is always poorly controlled. I hope you can give me some suggestions. :handshake

Nickel welding is more complicated than titanium and stainless steel welding. The welding environment, materials, processes, welder level, protection, interlayer temperature control, and weld bead cleaning are all very demanding.
Welding of special materials is no more difficult than common welding. Welding should be done more carefully. Those with high welding requirements require surfacing!
I don't know, but I should have a welding manual handy for the job.
