  • METHOD AND DEVICE FOR SEALING A JOINT GAP
    Publication number: 20190203838
    Abstract: A method for sealing a joint gap between mutually joined elements, at least one of which is a sheet, by applying a joint gap seal involves preheating an area of the joined elements to which the joint gap seal is to be applied. A polymer powder is introduced into a plasma jet to form a plasma and powder jet directed towards the preheated region of the elements. Polymer particles melted in the plasma and powder jet are deposited as joint gap seal.
