Method for producing a welded T-beam or I-beam profile

A method for producing a welded T-beam profile, the method comprising:

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

An installation for producing a welded I-beam profile, wherein the installation is configured to:

• provide a first flat material as a first flange of an I-beam profile,
• provide a second flat material as a second flange of the I-beam profile,
• provide a third flat material as a web of the I-beam profile,
• align and guide the first flange between first flange guiding rollers,
• align and guide the second flange between second flange guiding rollers,
• align and guide 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,
• fix 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,
• connect the first flange to a first longitudinal edge of the web by a first welding operation in a welding station,
• connect the second flange to a second longitudinal edge of the web by a second welding operation in the welding station,
• use, 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, and
• perform at least one of:
• 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
• 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.
