Also laser welding can be used:
You can use friction welding

Also diffusion bonding is one of the preferred methods for bonding these types of materials
I have very good experience with laser beam welding in vacuum with a thin copper layer. The sensor were He leackage tested up to 10-8 lmbar/s.
Dr Christian
Could you please send us the specifications of this sensor. Best regards
The aim was to weld a membran consisting of grade 12 to the sensor housing consisting of X6CrNiTi18-10. Requirements to the weld were He-tightness with an inner pressure of 400 bar. To weld Ti with SS an interlayer is needed. With a copper interlayer of 100 µm and due to the very low heat input of the process sound welds could be produce.
Dear Dr Christian could you please list the conditions o the welding experiment. best regards
