Patents Assigned to EMPA Swiss Federal Laboratories for Materials Science and Technology
  • Pre-welding analysis and associated laser welding methods and fiber lasers utilizing pre-selected spectral bandwidths that avoid the spectrum of an electronic transition of a metal/alloy vapor
    Patent number: 11484972
    Abstract: The present invention benefits from the determination that pre-selected spectral bandwidths that avoid the spectrum of an electronic transition of a metal/alloy vapor allow for welds substantially free from detritus that may discolor the weld. Accordingly, the present invention provides analytical methods, welding methods and fiber lasers configured to provide high quality metal/alloy welds.

  • Method for producing a strain gauge device
    Patent number: 10548488
    Abstract: The method for producing the strain gauge device (10) comprises a first stop of producing the band (12). The band (12) has flexibility at least in the measuring zone (36). Then a sensor (22) comprising at least one measuring strand (30) and changing electrical resistivity in dependence of the strain is produced and arranged on or in the band (12) without pre-tension. Afterwards the shape of the band (12) is changed into a retaining working shape and thereby the measuring strand (30) is stretched to an amount of pre-tension.
