The Influence of Various Laser Parameters on the Weld Seam Geometry

Lasers are increasingly used to weld various kinds of materials. However, it is important to control the formation process of the weld seam in order to receive the required joint design. For this reason it is necessary to get an extensive knowledge of the correlation between the laser parameters and the geometrical dimensions of the weld seam. The presented research investigates the weld seam formation process of two high strength steels using a high brilliant fiber laser.
