Abstract
An x-ray tube comprising a first electrode and a second electrode. The first and second electrodes are located in operative relationship with one another to generate x-rays when the electrodes are energized at their respective operating potential. An evacuated envelope encloses the first and second electrodes. The evacuated envelope includes a first envelope wall portion, a second envelope wall portion and an envelope weld member comprising an electrical conductor. The envelope weld member is in electrical communication so as to be at operating potential of one of the first and second electrodes when the x-ray tube is energized. The envelope weld member is adapted for vacuum tight joining to the first envelope wall portion and to the second envelope wall portion. The envelope weld member has an integral corona shield portion.
