PTOCESS OF PRODUCING LAMINAR STRUCTURE BY BONDING OF SHEET METAL BLANKS AFTER PRELIMINARY BONDING

摘要

The present invention relates to a method for manufacturing a laminated structure including metal plates overlapping each other, the method of manufacturing a laminated structure in which a plurality of metal plates corresponding to a plurality of metal plates and having a same thickness value overlap each other, (a Two adjacent sheet metal materials including the shortest sheet metal material among the sheet metal materials, and each of the plurality of sheet metal materials is the shortest sheet metal material, and the other sheet metal material among the two adjacent sheet metal materials. When superimposed on, pre-bonding by welding at predetermined portions of two adjacent sheet metal materials; (b) After preliminary joining, the laser beam generated from the laser cutting device is moved along the cutting line such that the laser beam spot formed on the exposed surface of the shortest plate metal material is moved along the cutting line. Cutting.
