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.
Claims19
A method for sealing a joint gap between mutually joined elements, at least one of which is a sheet, the method comprising:
- preheating an area of the mutually joined elements to which a joint gap seal is to be applied;
- introducing polymer powder into a plasma jet to form a plasma and powder jet directed towards the preheated area of the mutually joined elements;
- depositing polymer particles melted in the plasma and powder jet as the joint gap seal.
A device for applying a joint gap seal for sealing mutually joined elements, at least one of which is a sheet, the device comprising:
- a preparation zone configured to heat an area of the mutually joined elements;
- and
- a treatment zone, having a plasma nozzle and a powder supply, configured to generate a plasma and powder jet by introducing polymer powder into a plasma jet to form a plasma and powder jet directed towards the preheated area of the mutually joined elements and depositing polymer particles melted in the plasma and powder jet as the joint gap seal.
