Embodiment Construction

[0022] For the production of tailored strips (ie Tailored Strips), in particular steel strips, two, three or more cut strips 1 , 2 of different materials and / or thicknesses are welded together along their long sides. The cutting strips 1, 2 to be welded to each other are uncoated and exist in the form of a coil 3 (see figure 1 ). Firstly, the individual cut or steel strips 1 , 2 are leveled in separate straightening machines 4 , 5 after being unwound from the respective coil 3 . Next, frame processing takes place, wherein at least the frame to be welded of the cutting strips 1 , 2 can be run through a grinding machine and / or milling machine 6 , 7 in preparation for a subsequent welding process.

[0023] The cutting strips 1, 2 are conveyed to the same welding device 10 by means of separate conveyors (boosting units) and strip conveyors, in particular via strip conveyor wheels, or in the case of more than two cutting strips 1, 2 , sent to the welding device whose number is th...

Abstract

The invention relates to a method for producing tailor-made sheet strips (12), in particular steel strips, in which at least two sheet strips (1, 2) of different material quality and / or sheet thickness are continuously welded to each other along their length. In order that the sheet strips (1, 2) produced by such a method have a greater weld strength, uncoated sheet strips (1, 2) are used according to the invention as sheet strips to be welded. The tailor-made sheet strip (12) assembled from the uncoated sheet strips (1, 2) by welding is subsequently coated.

Description

technical field [0001] The invention relates to a method of manufacturing custom-made sheet and strip, in particular steel strip, in which sheet and strip of two different materials and / or sheet thicknesses are welded together along their long sides. Background technique [0002] Such a method is known, for example, from document EP 0 438 612 B1. It is used to manufacture so-called "Tailored Strips", that is, custom-made plate and strip, especially custom-made steel strip. For the manufacture of custom-made sheet metal strips, several, usually two or three cut-off strips of different materials and / or sheet thicknesses, which are each rolled up in coil form, are unrolled and aligned with each other on the long sides by means of a laser welded together. Customized sheet metal strips are used very successfully in steel lightweight construction, wherein the customized sheet metal strips are adapted from the outset to the load behavior occurring in the finished part (end produc...
