Laser welded tailored blanks - Technical delivery conditions

This European Standard describes the requirements for laser welded tailored blanks made of alloyed and unalloyed steels, of uniform or different steel grades and with or without metallic and/or organic coatings, having uniform or different sheet thickness. It applies only to the (Tailored Blanks) as-supplied condition of tailored blanks.
After the welding process, tailored blanks are further processed to pressed parts by forming operations under the responsibility of the processor. In the design of the component due consideration should be given to the fact that the weld seam is less formable in comparison to the base material.

Laserstrahlgeschweißte Tailored Blanks aus Stahlfeinblech - Technische Lieferbedingungen

Diese Europäische Norm beschreibt die Anforderungen an laserstrahlgeschweißte Feinbleche aus unlegierten und legierten Stählen gleicher oder unterschiedlicher Sorten mit und/ohne Oberflächenveredelung (Überzüge oder Beschichtungen) mit gleicher oder unterschiedlicher Blechdicke (Tailored Blanks). Sie gilt nur für den Anlieferungszustand der Tailored Blanks.
Tailored Blanks werden nach dem Schweißen in Verantwortung des Verarbeiters durch Umformung zum Bauteil verarbeitet. Bei der Auslegung des Bauteils sollte der geringeren Umformbarkeit der Schweißnaht im Vergleich zum Grundwerkstoff Rechnung getragen werden.

Flans raboutés laser - Conditions techniques de livraison

La présente Norme Européenne décrit les exigences pour les flans raboutés laser élaborés à partir d’aciers alliés et non alliés de nuances identiques ou différentes avec ou sans revêtements métalliques et/ou organiques d’épaisseurs identiques ou différentes. Elles s’appliquent seulement aux flans raboutés.
Après le processus de soudage, les flans raboutés sont ensuite transformés en pièces embouties au moyen d’opérations de formage qui sont de la responsabilité du transformateur. Durant la conception de la pièce, il faut tenir compte du fait que le cordon de soudure a une formabilité moindre en comparaison de celle du métal de base.

Lasersko varjeni posebej prilagojeni spoji - Tehnični dobavni pogoji

Ta tehnični dobavni pogoj opisuje zahteve za lasersko varjene posebej prilagojene spoje, izdelane iz legiranih in nelegiranih jekel, enotnih ali različnih razredov jekla s kovinskimi in/ali organskimi prevlekami ali brez njih, enotnih ali različnih debelin pločevine. Uporablja se samo za posebej prilagojene spoje v stanju, kot so dobavljeni. Po postopku varjenja se posebej prilagojeni spoji nadalje obdelajo v stisnjene dele s postopki oblikovanja, za katere je odgovoren obdelovalec. Pri načrtovanju sestavnega dela je treba skrbno upoštevati, da se zvar težje oblikuje kot osnovni material.

EN 10359:2015 (E) 4 1 Scope This European Standard describes the requirements for laser welded tailored blanks made of alloyed and unalloyed steels, of uniform or different steel grades and with or without metallic and/or organic coatings, having uniform or different sheet thickness. It applies only to the (Tailored Blanks) as-supplied condition of tailored blanks. After the welding process, tailored blanks are further processed to pressed parts by forming operations under the responsibility of the processor. In the design of the component due consideration should be given to the fact that the weld seam is less formable in comparison to the base material. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 10131, Cold rolled uncoated and zinc or zinc-nickel electrolytically coated low carbon and high yield strength steel flat products for cold forming — Tolerances on dimensions and shape EN 10143, Continuously hot-dip coated steel sheet and strip — Tolerances on dimensions and shape ISO 2768-1, General tolerances — Part 1: Tolerances for linear and angular dimensions without individual tolerance indications 3 Terms and definitions For the purposes of this document, the following term and definition applies. 3.1 tailored blanks laser welded metal sheets of uniform and/or different thickness and/or uniform or different steel grades, both with and without surface coating 4 Requirements As far as the properties of the components are concerned, the general rules of engineering apply. The suitability of tailored blanks for the processes of the customer is guaranteed in case of appropriate execution of the welding seam, suitable positioning of weld seam in the part to be formed and appropriate lay out of sheet thicknesses and steel grades under taking into consideration the requirements of known further processing steps. The criteria laid down in Table 1 have proved to be a practical basis for ordering. Additional specific deviations are admissible and have to be agreed upon at the time of ordering. 5 Tolerances on dimensions and shape Regarding tolerances on dimensions and shape the agreements of EN 10131 and EN 10143 shall apply for cold rolled and surface coated wide coils, cut to length sheets and slit coils, which are used for the manufacturing tailored blanks. The relevant tolerance classes for width, flatness and thickness have to be agreed upon between producer of tailored blank and steel producer. For the general tolerances regarding lengths, angles, coaxiality and symmetry, the precision class c according to ISO 2768-1 shall apply. SIST EN 10359:2015

EN 10359:2015 (E) 5 If not all edges of the blank were cut, the definition of the dimension has to be according to EN 10143 and EN 10131 also. Specific requirement and other beyond that valid special customer agreement have to be agreed upon between producer of tailored blank / steel producer and customer. 6 Destructive testing of weld joints 6.1 Cup test Destructive testing of weld joints with cup test is considered as best practice procedure. The evaluation of weld quality is done according to the pictures in Table 2. Frequency of the cup test is minimum once a run. 6.2 Cross section Samples shall be taken minimum 5 mm from both ends of welds. For measu
