    • Manufacturing method, welding arrangement and door frame structure for a door frame (21) of a windmill tower (10), wherein a hole (15) is made in the tower shell (10) for the door and a door frame is placed in the hole and welded on the shell. In the method, the shape of the door frame for the shell and the shape of the surface of the shell at the opening (15) to be made are measured with a measuring sensor (40). Based on the measurements, a cutting torch (41) is controlled so that an opening corresponding to the shape of the door frame is cut in the shell and bevels (16, 17) are cut in the edge of the opening on both sides. The door frame is welded on the shell with a weld (24), such as a double bevel, double J or square butt weld, from the inside and the outside of the shell.
    • 一种用于风车塔(10)的门框(21)的制造方法,焊接布置和门框结构,其中在用于门的塔壳(10)中形成有孔(15),并且门框架 孔和焊接在壳上。 在该方法中,用测量传感器(40)测量用于壳体的门框的形状和壳体在开口(15)处的表面的形状。 基于这些测量,控制切割炬(41),使得在壳体中切割与门框的形状相对应的开口,并且在两侧的开口的边缘上切割斜面(16,17)。 门框从外壳的内外侧焊接在外壳上,具有焊接(24),例如双斜面,双J或方形对接焊缝。
