Need welding procedure on how to weld Tantalum, never welded with this material, I am at a dead end and need help.
Tried everything, need to talk to someone that has welded with this material for some pointers.
What will you be welding? What process are you using?
Tantalum is usually welded via resistance welding or with a GTAW process in a vacuum chamber. Helium or argon/helium mixes are common. No filler is typically used.
If you do a search on welding tantalum or refractory metals in general, it'll get you in the ballpark.
