ABSTRACT:
A diaphragm and a first tubular member are combined into a one-piece transducer diaphragm element by electron beam welding. The first tubular member is formed as a first heat sink contacting one major surface of the diaphragm. A second tubular member is provided as a second heat sink in contact with the opposite major surface of the diaphragm. The diaphragm is sandwiched between the first and second tubular members into a composite structure laterally delimited by the peripheries of the diaphragm and the first and second tubular members. Ends of the first and second tubular members and a peripheral portion of the diaphragm are welded with an electron beam into a fillet-type welding joint monolitically unifying the diaphragm and first and second tubular members. Heat is axially removed from the diaphragm through the mentioned first and second heat sinks during the electron beam welding.
