On the basis of location information which signifies a clamp location of a jig with respect to a new workpiece, new workpiece cross-section information is recognized in the clamp location. Next, a search is carried out among existing workpiece cross-section information for information similar to the recognized new workpiece cross-section information. Next, jig information is selected which is linked to the found workpiece cross-section information. Next, the selected jig information and the location information are linked and set to new workpiece design information.

A method of welding a support on a slide profile, which comprises: a) providing a support having a wall with an inner face, and providing a profile having a wall with an outer face, b) positioning the interface support with the inner face of its wall against the outer face of the wall of the profile, c) creating a welding joint between the wall of the support and the wall of the profile by moving a laser beam relative to the wall of the profile, while keeping the laser beam in a position such that it successively passes through, from an emitting source: the wall of the profile, then the wall of the support, while remaining within the material of the wall of the support.

The present disclosure relates to the technical field of production of H-shaped steel and discloses a production line of H-shaped steel and a production method. By arrangement of the assembly zone in which a welding line is arranged and the welding zone in which a welding line is arranged, a process layout of assembly and welding flow type machining production line can be formed. Assembly and welding of a stiffening plate are operated independently, and a carrying robot, a spot welding robot and a welding robot are movable between stations. A transfer device transfers an H-shaped workpiece in the process of feeding, machining and discharging, thereby implementing flow type machining, which can effectively improve machining efficiency. Through the production method, the assembly and welding flow type machining of the stiffening plate can be implemented, thereby effectively improving machining efficiency.

A method for producing a supporting element for a transportation device or vehicle, having steps of providing a flat base chord made of a first material having a first surface and a second surface, applying at least one layer of at least one second material to the first surface using a friction-based application or welding method, and machining the at least one layer of the second material to produce a desired profile cross section of the supporting element, wherein the first material and the second material are different metallic materials.

A multi-tubular beam for a vehicle, such as a vehicle structure or a bumper reinforcement, includes an elongated beam formed with a metal sheet. The metal sheet has a central section and outer sections extending along a length of the metal sheet. The outer sections are disposed in opposing directions from the outer edges of the central section to provide adjacent first and second tubular portions. The central section forms a common center wall between the adjacent first and second tubular portions. A first edge portion of the metal sheet is disposed along and in parallel alignment with the center wall. The first edge portion is attached to the center wall at a first weld joint to form the first tubular portion. The first weld joint includes a weld material that extends through a thickness of the center wall and into a thickness of the first edge portion.

A prefabricated column assembly includes a hollow tubular column having a longitudinal axis. A gusset plate assembly includes a plurality of gusset plates connected to the column and extending laterally outward from the column in planes generally parallel to the longitudinal axis of the column. A first pair of the gusset plates extends laterally outward from the column along a first axis and defines a space for receiving an end portion of a first beam for mounting the first beam on the first pair of gusset plates. A second pair of the gusset plates extends laterally outward from the column along a second axis that is nonparallel and non-coincident with the first axis. The second pair of gusset plates defines a space for receiving an end portion of a second beam for mounting the second beam on the second pair of gusset plates to provide a bi-axial joint connection.

A beam-end component welding fixture including a stand having a central horizontal axle mechanism and a housing. A handle is mounted on a first end portion of the axle mechanism and a rotatable plate structure is mounted on a second end portion of the axle mechanism. A column connecting simulator is attached to the plate structure and configured to support a beam-end component.

A galvanized steel sheet includes: a steel sheet having a chemical composition satisfying an equivalent carbon content Ceq of 0.35% or more and less than 0.60%, and a specified steel microstructure; and a galvanized layer on a surface of the steel sheet. The retained austenite has a solute C content of 0.6% or more by mass, and retained austenite grains with an aspect ratio of less than 2.0 constitute 50% or more of all retained austenite grains. In 90-degree bending at a curvature radius/thickness ratio of 4.2 in a rolling (L) direction with respect to an axis extending in a width (C) direction, an L cross section in a 0 to 50 μm region from a surface of the steel sheet on a compression side has a number density of voids of 1000/mm.sup.2 or less, and the galvanized steel sheet has a tensile strength of 590 MPa or more.

A device for welding may include a track configured to surround a workpiece. The device for welding may also include a cart configured to contact the track such that the track guides the cart around the workpiece. The cart may include a frame and a welding torch receptacle. The welding torch receptacle can be attached to the frame. The welding torch receptacle may be configured to maintain a tip of the welding torch at a set distance away from the workpiece while the cart moves around the workpiece.
