<p>The invention relates to a window frame reinforcement (2) to be combined with the main reinforcement of a door of an automobile comprising an upper part (2a) which comprises at least one upper horizontal sector and two side sectors demarcating a hole (2c) for a window top-wise and side-wise; a horizontal lower part (2b); and a waist reinforcement (3) arranged in correspondence with the lower part (2b), in which the upper part (2a) and the lower part (2b) are independent pieces joined to one another by means of weld joint (4,4a,4b,4c) and the waist reinforcement (3) is formed in a horizontal sector of the lower part (2b).
The frame can be manufactured by means of a method which comprises welding a first initial format (2a') and a second format (2b') to one another to obtain a combined format (2') and forming the upper part (2a) from the first initial format (2a') and the lower part (2b) with the waist reinforcement (3) from the second initial format (2b'). When the initial formats (2a',2b') are of different materials, TBW welding, FSW welding, brazing welding, CMT welding can be used depending on the materials of the initial formats (2a',2b').</p> |
