METHOD FOR JOINTING METAL FOILS IN A SUPERPOSED WAY AND JOINT STRUCTURE

摘要

The purpose of the present invention is to provide a method for overlapping a metal foil and a joint structure capable of certainly overlapping the metal foil by using a general-purpose non-contact welding device. The method for overlapping a metal foil (12) according to the present invention includes a temporary fixing process for temporarily fixing adjacent metal foils (12) to be closely attached while a plurality of metal foils (12) is overlapped, and a welding process for non-contact welding a contact region (18) temporarily fixed among a plurality of metal foils (12), thereby obtaining the joint structure (200).
