Method for manufacturing a laminar construction panel comprising a first metal plate (1), a second metal plate (2), and an acoustic insulation layer (3) interposed there between. The first metal plate and the second metal plate are connected to each other by means of a number of locally welded joints, that are distributed over the laminar construction panel, and which extend through the area of the acoustic isolation layer. The welded joints are formed by means of stud welding, wherein one of the metal plates is provided with welding openings (4), and a welding pin (7) is pushed through the isolation layer, against the other metal plate. The welded joints may also be formed by means of spot welding, wherein both metal plates are brought into electrical connection with the spot welding equipment, and the metal plates locally are pressed toward each other in such a way that mutual electrical contact is made.
