TECHNICAL FIELD
This invention relates to a method for welding beryllium.
This invention was made with government support under Contract No. W-7405-ENG-36
awarded by the U.S. Department of Energy. The government has certain rights in the invention.
BACKGROUND ART
There have been developed various methods for joining pieces of beryllium. These
methods include: partially merging a welding film of silver, gold, nickel or copper onto a
reinforcing unit of stainless steel which is then diffusion welded onto the beryllium (U. S. Patent
5,161,179); diffusion bonding the beryllium pieces by coating at least one surface of at least one
of the beryllium pieces with nickel, contacting the beryllium pieces, exposing the pieces to lower
than ambient environmental pressure, and then under pressure heating the surfaces while
decreasing the applied pressure (U. S. Patent 3,964,667); and brazing or diffusion-welding
beryllium pieces with one of a family of brazing alloys of aluminum with magnesium, or rare
earth, or silicon, or tin, or copper, or palladium, or gallium, or silver, or bismuth or strontium
(U. S. Patent 4,040,822).
It is difficult to join very thin pieces of beryllium to each other because the heat of
welding or brazing deteriorates the mechanical strength of the thin beryllium pieces. It is
difficult to join pieces of beryllium thicker than about 0.1 inches to each other. Attempts to
autogeneously weld beryllium in thicknesses common for industrial uses results in cracking of
the beryllium.
It would be advantageous to be able to quickly and easily join beryllium pieces using a
welding process so that strong, lightweight aircraft, space components or satellite parts could be
fabricated from beryllium. There is still a need for ways of joining beryllium pieces directly to
each other without regard for the thickness of the beryllium pieces.
It is an object of this invention to provide a method for joining pieces of beryllium.
It is another object of this invention to provide a method of fabricating parts from
beryllium.1
