  • Method for laser welding two coated workpieces
    Patent number: 12409514
    Abstract: A method for laser welding two coated workpieces includes positioning an upper workpiece and a lower workpiece on top of each other and passing a first laser beam over the upper and lower workpieces from a side of the upper workpiece so as to at least partially evaporate the respective coating of each of the workpieces on their facing sides along a depletion trace. A second laser beam is passed over the workpieces from the side of the upper workpiece so as to melt a material of the two workpieces within the depletion trace, and thereby weld the workpieces to one another. In the first laser passing, the first laser beam melts the material of the upper workpiece, so that a web of non-melted material of the upper workpiece remaining between the melted material of the upper workpiece and the facing side of the upper workpiece.

  • Method of making a flexible closure incorporating an alarm system
    Patent number: 5677674
    Abstract: A flexible closure, for use in an alarm system is provided in which a conductive sensing element is interlaced with fiber matrix material to provide a network over at least part of the closure. The interlacing is preferably by means of knitting a conductive wire together with a yarn which forms the matrix of the closure. The closure may further include a protective outer layer on one or both faces of the closure.
