Welding Titanium GR1 to GR 12
Welding Titanium GR1 to GR 12
(OP)
I have a repair where I need to join GR1 to GR12. The application is cladding over carbon steel. Both Ti grades are bonded to the carbon steel and I plan to replace a small section which has failed in service due bad welding practise. The repair weld would laid on to a GR12 backing bar in the root of the butt weld.
I was planning to use GR12 filler for the PQR qualification. Does anybody see an issue with this selection?

The repair itself may be another issue.
