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   Prem S Nautiyal
