[MW:13296] Back purge for CuproNickel welding

Hi friends
 
I am establishing a welding procedure for welding of 90-10 Cu-Ni 6mm thick tubes, UNS C70600 as per ASME SecIX.
All joints are single sided joints and i will be welding them with TIG: ER CuNi filler wire.
 
My only query was that do i need to back purge the weld joints ?
 
Regards
