X-Ray Device Comprising A Crack Resistant Weld
view source
US Patent:

6335512, Jan 1, 2002
Filed:

Jul 13, 1999
Appl. No.:

09/352393
Inventors:

John Warren - Waukesha WI
Paul Neitzke - Menomonee Falls WI
Craig Higgins - Milwaukee WI
Assignee:

General Electric Company - Schenectady NY
International Classification:

B23K 900
US Classification:

219137WM
Abstract:

A welding method that enables the joining of at least two dissimilar, metallic alloys to form a weld that is free of cracks is disclosed. The method incorporates a pure (99. 00% minimum by weight) nickel fill-wire, integrally assembled into the joint between the two alloyed metals to be joined. The alloys joined by this method are an iron-based, low expansivity, gamma-prime strengthened superalloy (i. e. , IncoloyÂ) and a high carbon, powder metallurgical tool steel high in refractory metal alloying agents (i. e. , CPM REX 20). Welding of the joint results in the formation of a nickel rich region within the weld, thus âinoculatingâ the weld against cracks. The weld joint formed by the method of the present invention can be used in the fabrication of a rotating anode bearing shaft assembly for use in an x-ray generating device.

US Patent:

6553097, Apr 22, 2003
Filed:

Jan 12, 2001
Appl. No.:

09/759369
Inventors:

Steve Hansen - Port Washington WI
Douglas J. Snyder - Brookfield WI
Thomas Ebben - Sullivan WI
John Warren - North Reading MA
Paul Neitzke - Menomonee Falls WI
Craig Higgins - Eau Claire WI
Assignee:

GE Medical Systems Global Technology Company, LLC - WI
International Classification:

H01I 3500
US Classification:

378144, 378143
Abstract:

An x-ray tube and x-ray system including an anode assembly having a shaft with a first end and a second end, a target connected to the first end of the shaft, and a rotor connected to the second end of the shaft. The anode assembly further having spaced-apart bearings rotatably supporting the shaft. The shaft, target, and rotor positioned relative to each other such that the center of gravity of the combination of the shaft, the target, and the rotor is positioned between the bearings. Additionally, the target and rotor may be flexibly interconnected allowing the beneficial use of gyroscopic effects.
