  • Welding device for two work pieces to be joined together by a weld seam which is closed in itself
    Patent number: 6288359
    Abstract: The invention relates to a welding device operating by laser for two workpieces (1, 2) to be connected to one another via a self-contained, continuously extending weld seam (N). The welding device comprises a focusing optical system (7) having a seam follow-up sensor (10) and is borne by a pivoting arm (11), so that the focussing optical system (7) describes a circular path in relation to the workpieces (1, 2). The positioning of the focusing optical system (7) on the pivoting arm (11) is corrected by means of a drive (13) in dependence on the measuring result of the seam follow-up sensor (10).
