1. A method for producing a welded I-beam profile, the method comprising:
providing a first flat material as a first flange of an I-beam profile,
providing a second flat material as a second flange of the I-beam profile,
providing a third flat material as a web of the I-beam profile,
aligning and guiding the first flange between first flange guiding rollers,
aligning and guiding the second flange between second flange guiding rollers,
aligning and guiding the web between web guiding rollers, wherein the web is arranged between the first flange and the second flange in a plane that is perpendicular to the first flange and the second flange for forming the I-beam profile,
fixing at least one of the first flange, the second flange, or the web by the web guiding rollers in two spatial directions in such a way that only a movement in a longitudinal direction is possible,
connecting the first flange to a first longitudinal edge of the web by a first welding operation in a welding station, and
connecting the second flange to a second longitudinal edge of the web by a second welding operation in the welding station, wherein the method comprises at least one of:
performing the first welding operation as through-welding from a top side, facing away from the web, of the first flange to form a weld seam; or
performing the second welding operation as through-welding from a top side, facing away from the web, of the second flange to form a weld seam, and
using, at least for some time, a slide to move the first flange, the second flange, and the web, wherein the slide is arranged upstream of the welding station in a run-through direction, lies against the first flange and the second flange and the web and performs the movement as an advancing movement in the longitudinal direction.
