Abstract
Shaped metal deposition apparatus comprises a mounting head for mounting a shaped metal deposition device, an inert gas shield for providing an inert atmosphere around shaped metal deposited in use by the shaped metal deposition device, and a rotatable coupling between the mounting head and the inert gas shield to permit relative rotation therebetween.
Claims19
A shaped metal deposition apparatus for providing an inert atmosphere to deposited metal comprising:
- a mounting head configured to provide an inert atmosphere around shaped metal deposited by a shaped metal deposition device in a first region;
- an inert gas shield configured to provide an inert atmosphere around shaped metal deposited by the shaped metal deposition device in a second region, the second region being different than the first region;
- and
- a rotatable coupling disposed between the mounting head and the inert gas shield to permit relative rotation therebetween, wherein
- the rotatable coupling includes:
- a first gas transfer plate connected to the inert gas shield, and
- a second gas transfer plate connected to the mounting head, the first gas transfer plate and the second gas transfer plate being parallel to one another;
- and
- the rotatable coupling defines a gas transfer path for transferring inert gas from the inert gas shield to the mounting head.
