A method for producing a welded I-beam profile includes providing a first flat material as a first flange of the I-beam profile, providing a second flat material as a second flange of the I-beam profile, and providing a third flat material as a web of the I-beam profile. The method includes aligning and guiding the first flange between first flange guiding rollers, aligning and guiding the second flange between second flange guiding rollers, and aligning and guiding the web between web guiding rollers. The web is arranged between the flanges in a plane that is perpendicular to the flanges for forming the I-beam. The method includes 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.

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

A method is provided for transporting flat materials to be welded together, specifically a first flange and/or a second flange and a web for producing a beam through a welding station. The flat materials are aligned and guided by rollers. A slide is arranged upstream of the welding station in the run-through direction and a gripper is arranged downstream of the welding station. The slide introduces the flat materials into the welding station and moves them as far as a first position by means of a pushing movement at an advancement speed. The gripper grips the flat materials at the first position, and pulls the flat materials out of the welding station at the pulling speed and moves them as far as a second position by means of a pulling movement. The slide is arranged upstream of the welding station and the gripper is arranged downstream of the welding station.

In a method for cutting structural components to be joined by laser radiation that is guided by a computer-controlled manipulation system provided with a nominal path for each structural component corresponding to a joining line that is curved as a result of at least one of the structural components being three-dimensionally shaped, the structural component surfaces of the structural components including the joining line are determined measuring technologically. Based on measuring results, the nominal path corresponding to a penetration line of the structural components to be joined is calculated. A marking is formed on a first one of the structural component surfaces. When performing the cut on the structural component surface provided with the marking, the resulting cutting gap and the marking are determining measuring technologically. When a deviation of the cutting gap from the nominal path is detected, the manipulation system is controlled to correct the deviation.
