Abstract
A gas leakage seal for a turbine, including first and second cloth layers having woven warp and weft wires, wherein the first and second cloth layers are brazed together by a flux paste whereby the cloth layers have their edges aligned and the brazing substantially seals gaps between the wires along substantially the entire length and width of the brazed together cloth layers. Weld beads having a thickness greater than the combined thickness of the brazed together cloth layers connect the edges of the cloth layers along their length. The turbine includes two members with aligned recesses in which opposite of the weld beads are received. The seal is made by brushing a nickel and/or cobalt based flux paste on one side of one of the cloth layers, brazing that cloth layer to a side of the second cloth layer to substantially seal the gaps between the wires, and creating weld beads with an electron beam to connect the edges of the cloth layers along their length.
