Process for producing a frameless door for a motor vehicle and the frameless door produced in such a manner

摘要

A method for production of a door for a motor vehicle is provided for at least one door inner piece (1) and at least one door outer sheet (2), which are produced separately from each other and are then combined into one. The method includes making the door inner piece entirely or partially of cast aluminum. The door outer sheet is made of aluminum. The edge (13) of the door outer sheet (2) is folded towards the door inner piece (1). The folded edge (13) of the door outer sheet (2) is brought into contact with a mating surface (12) of the outer edge (11) of the door inner piece (1). The door inner piece (1) and the door outer sheet (2) are connected to each other by a laser-welded seam (7) produced by a laser beam directed in the gap between the mating surface (12) and the edge (13).
