Method for manufacturing a laminar construction panel

Method for manufacturing a laminar construction panel, said method comprising the following steps:

• connecting a first metal plate (1) to a second metal plate (2) by means of a number of spaced apart welded joints distributed over the laminar construction panel and which extend through an area of an intermediate acoustic insulation layer (3),
• forming the number of spaced apart welded joints by means of stud welding, the stud welding method comprising:
• providing said first metal plate (1), acoustic insulation layer (3) and second metal plate (2), wherein the second metal plate has welding openings (4) at locations where the spaced apart welded joints will be;
• providing electrical stud welding equipment or another suitable welding current source, of which a first welding current connection (5) is electrically connected to the first metal plate and/or the second metal plate, and the electrical stud welding equipment being provided with a welding pin (7) to be connected with a second welding current connection (6), the welding pin having a cross section smaller than a cross section of the welding openings (4);
• performing a stud welding action for each welding opening, the welding pin is inserted into the welding opening, subsequently pushed through the acoustic insulation layer, and pressed onto a metal surface of the first metal plate in such a way that a welding current flows through the welding pin and the first metal plate, thereby melting and joining together metal (8) of the welding pin and the first metal plate by that welding current, which stud welding action is continued until a space (9) between the welding pin and the welding opening is filled with molten metal (10) of the welding pin and the first and/or second metal plate.
