Zusammenfassung:	A method is disclosed for welding a first part and second part together. A spacer bead is first formed on the first part by directing a laser beam on one side of the first part. The second part is then assembled to the one side of the first part. The second part is then welded to the first part by directing a second laser beam in a partially circular pattern adjacent the spacer bead. An end portion of the weld terminates radially inside the partially circular pattern.
