A first abutting surface, a first welding surface, a first facing surface are formed in a differential case. A second abutting surface, a second welding surface, and a second facing surface are formed in a differential ring gear. In an installing step, the first abutting surface and the second abutting surface are inserted, positions of the differential case and the differential ring gear are determined in an axial direction, a separation portion that spaces the first welding surface and the second welding surface away from each other and that has a non-linear portion is formed, and a void is formed between the first facing surface and the second facing surface. In a welding step, a laser is irradiated to the separation portion and the first welding surface and the second welding surface are welded.

A system for welding a first component to a second component. The system includes a first laser head configured to emit a first laser beam and be movably disposable on a first side of the first component. The system further includes a second laser head configured to emit a second laser beam and be movably disposable on an opposing second side of the first component. The system further includes a controller configured to independently control a first power of the first laser beam and a second power of the second laser beam. The controller is also configured to independently and simultaneously control movement of the first laser head and movement of the second laser head relative to the first component.

A welding method includes: emitting a laser beam to a workpiece including a metal; and welding a portion of the workpiece to which the laser beam is emitted by melting. The laser beam includes a main power region and at least one auxiliary power region, power in the main power region is equal to or higher than power in each of the at least one auxiliary power region, and a power ratio of the power in the main power region and a total of the power in the at least one auxiliary power region is within a range of 144:1 to 1:1.

A component arrangement and a method for producing the component arrangement are provided. The component arrangement includes a first component and a second component, which are arranged in an overlapping arrangement and are connected by a laser fillet weld and at two fixing points arranged laterally offset from the laser fillet weld, one of the components is provided with at least one projection, which projects in the direction of the other component and which is arranged and formed such that, when the components are positioned correctly in relation to one another and are pressed together at the fixing points, a flange portion of the first component, set at an angle in the region of the laser fillet weld to be formed, is pressed onto the second component by way of the component edge. For sealing the component arrangement, the fixing points are arranged set back into the overlapping region with respect to the laser fillet weld, and at least between the fixing points there is formed a continuous bonding region, in which the first and second components are bonded to one another.
