A busbar includes: a plurality of members that are platy; and a welding area in which two of the members are welded, the welding area being linear and extending in a first direction, the welding area being provided approximately between both ends of at least one of the two members in the first direction.

The disclosure relates to methods and systems for deep welding a workpiece, a surface of the workpiece being irradiated by a first laser beam and a second laser beam. In a workpiece surface plane (OE) a first beam width B1 of the first laser beam is larger than a second beam width B2 of the second laser beam and in at least the workpiece surface plane (OE) the second laser beam lies inside the first laser beam. The intensity of the first laser beam alone is sufficient to produce a keyhole in the workpiece. The keyhole produced in the workpiece has a width KB in the workpiece surface plane (OE), KB substantially equaling B1, and B2≤0.75*KB. The methods and systems provide good seam quality, high penetration depth, and high welding speed.
