    Patent number: 9849542
    Abstract: In a method for preparing a workpiece for subsequent laser welding, a recessed structure in the form of at least two grooved line elements is formed by a laser beam in a surface of the workplace, with the line elements having a common starting point from which the laser beam moves onwards to produce the line elements. Solidifying material melt of the workpiece is hereby accumulated in an area of the starting point to produce a nub-like elevation sized to extend out beyond the surface of the workpiece.
