Abstract: The invention provides an economical laser welding method for joining two metal materials with a fillet joint. The method reliably compensates for tolerances between the two materials and can be used in various light conditions and production environments. In addition, the method does not require additional equipment for purposes of seam tracking. Instead, the method includes oscillating a laser beam, for example in a “figure 8” pattern, while moving the laser beam laterally along an interface between the two materials. The width of the fillet joint is increased compared to the fillet joint that would be formed using a non-oscillating laser beam, and thus compensates for the tolerances. The width of the fillet joint depends on the oscillation amplitude of the laser beam, rather than the beam size.
