| Zusammenfassung: | The method comprises arranging two band-shaped sheet-metal strips that are made of different materials next to each other and then welding with one another in their extension direction by friction stir welding or laser welding process. The sheet-metal strips are provided by reels, are welded under continuous feed motion by a stationary friction stir welding device or laser welding device and are welded to each other with different sheet metal thickness. The edges of the sheet-metal strips are welded with one another without pretreatment.
Die Erfindung betrifft ein Verfahren zum Herstellen eines bandförmigen Verbundhalbzeugs (12), bei welchem wenigstens zwei bandförmige Blechstreifen (14, 16, 18) aus unterschiedlichen Materialien nebeneinander angeordnet werden und in ihrer Erstreckungsrichtung miteinander verschweißt werden, wobei die Verschweißung durch Reibrührschweißen oder durch Laserschweißen erfolgt. |
