Laser welded tailored blanks - Technical delivery conditions

This document specifies the requirements for laser welded tailored blanks (LWB) made of steels for all cold or hot forming processes.
This document is applicable to all steel grades with or without metallic and/or organic coatings, having uniform or different sheet thickness, welded with or without extra material addition.
After the welding process, LWB are further processed to pressed parts by forming operations under the responsibility of the processor.

Laserstrahlgeschweißte Tailored Blanks aus Stahlfeinblech - Technische Lieferbedingungen

Dieses Dokument legt die Anforderungen an lasergeschweißte Tailored Blanks (LWB) aus Stählen für alle Kalt- und Warmumformverfahren fest.
Dieses Dokument ist anwendbar für alle Stahlsorten mit oder ohne metallische und/oder organische Beschichtungen, mit gleichmäßiger oder unterschiedlicher Blechdicke, geschweißt mit oder ohne Zusatzwerkstoffzugabe.
