Abstract
A method of joining at least one first metal sheet and a second metal sheet by laser welding includes at least partially stacking the at least one first metal sheet and the second metal sheet on top of one another to form an overlap region and welding together the at least one first metal sheet and the second metal sheet in the overlap region along an oscillating line. Welding along an oscillating line creates a longer weld seam in comparison to welding along a straight line, thereby increasing the strength of the weld seam.
Claims21
A method for joining at least one first metal sheet and a second metal sheet by laser welding, the method comprising:
- at least partially stacking the at least one first metal sheet and the second metal sheet on top of one another to form an overlap region;
- and
- welding together the at least one first metal sheet and the second metal sheet in the overlap region along an oscillating line to form a weld seam.
A method for joining at least three sheets by laser welding, the method comprising:
- at least partially stacking a first sheet, a second sheet and a third sheet on top of one another in such a way that they form an overlap region;
- providing a laser above the overlap region;
- and
- welding together the first sheet, the second sheet and the third sheet in the overlap region along an oscillating line,
- wherein the first sheet, the second sheet and the third sheet are stacked with decreasing thickness in the direction towards the laser.
(canceled)
A vehicle component comprising:
- a first sheet;
- a second sheet at least partially stacked on top of the first sheet to form an overlap region;
- and
- a weld seam provided in the overlap region for securing the first sheet to the second sheet, the weld seam being formed along an oscillating line.
