METHOD FOR TRAVERSING A WELDING CONTOUR MULTIPLE TIMES USING MULTIPLE LASER SPOTS

A method for welding at least two aluminum-containing components includes subdividing an output laser beam into multiple partial beams directed onto the at least two components, so that multiple laser spots are generated on a surface of the at least two components, and traversing a welding contour w...

Zusammenfassung:	A method for welding at least two aluminum-containing components includes subdividing an output laser beam into multiple partial beams directed onto the at least two components, so that multiple laser spots are generated on a surface of the at least two components, and traversing a welding contour with the multiple laser spots on the surface of the components. Centers of at least three laser spots of the multiple laser spots are arranged in a ring formation. The output laser beam is generated by a multifiber, so that each laser spot of the multiple laser spots on the surface of the components has a core portion and a ring portion. The welding contour is traversed at least partially a second time after the welding contour has been traversed a first time.
