Method for overlap welding of sheet-metal components with metallic coatings

The method for overlap laser welding of sheet-metal components with metallic coatings involves use of two beams (4, 4'). The focal points of these beams are positioned close to one another on each side of the welding line so that in the welding direction one is slightly in front of the other. A...

Zusammenfassung:	The method for overlap laser welding of sheet-metal components with metallic coatings involves use of two beams (4, 4'). The focal points of these beams are positioned close to one another on each side of the welding line so that in the welding direction one is slightly in front of the other. As a result, the weld bath is broadened and the vapour of the coating metal can escape without hindrance.
