Description
technical field [0001] The invention relates to a film welding machine and a welding method, in particular to a film high-temperature welding machine and a welding method for performing high-temperature welding in a continuous walking mode of a welding head. Background technique [0002] A solar sail is a thin film with a large area, flat surface, smooth surface, and no spots or wrinkles. It can provide a steady stream of power for spacecraft by reflecting solar photons, so it has become a new research direction for space propulsion. Polyimide film has become one of the preferred materials for solar sails because of its light weight, high and low temperature resistance, and high strength. However, due to the limitation of production scale, large-area polyimide films need to be obtained by welding. [0003] According to the relationship between the film material and the welding head during welding, the existing thin film welding machines can be roughly divided into two types...
