Abstract

METHOD OF WELDING LAMINATED METAL FOILS Provided is a method of welding laminated metal foils that can prevent blowholes and 5 spatter from being formed. It is a method of welding laminated metal foils sandwiched between a pair of metal plates to the pair of metal plates. The method of welding laminated metal foils sandwiched between a pair of metal plates to the pair of metal plates includes locally pressing and crimping the laminated metal foils sandwiched between the pair of metal plates at a welding point in a laminating direction, and welding the crimped pair of metal plates and 10 laminated metal foils at the welding point.
