Laserschweissverfahren für beschichtete Stahlbleche |
摘要 |
A top (1) piece of sheet steel is welded to a bottom (2) piece of sheet steel by means of a fillet weld. The top piece is welded along its front side and the bottom piece along its surface. A laser beam (3) is guided along a channel so as to create a laser beam fillet weld. Since the top and bottom pieces of sheet steel each have a zinc coating, this coating evaporates and oozes in a specific direction (5). Independent claims are also included for the following: (a) A deep-drawn piece of sheet steel as a piece of motor car bodywork formed from two pieces deep-drawn thin sheet steel linked by a welded joint; (b) and for deep-drawn pieces of sheet steel to be interlinked to a piece of motor car bodywork by a laser welded joint. |
