Abstract
A method of optimizing laser welding of two different metals is disclosed herein. In some embodiments, a method for optimizing laser welding of two different metals comprising laser welding a plurality of samples comprising a first metal and a second metal to form a weld between the first metal and the second metal, the weld having a molten area, wherein each sample is laser welded using a different line energy, measuring the content of an intermetallic compound produced by the laser welding in the molten area of the weld in each sample, and determining the line energy of the laser that results in the content of the intermetallic compound produced in the molten area of the weld being less than 10%.
