Coated metal sheets are laser welded together forming high strength bond. A powdered flux material is applied to at least one surface of one of the coated sheets of metal. The coated sheets of metal are pressed together with the powdered flux material therebetween defining a gap. A laser beam forms a laser weld wherein a portion of the gases produced during the forming of the laser weld escape through the gap and a portion of the gases reacts with the powdered flux material. The powered flux material can be applied by first spraying one surface of the coated metal sheets with an anti-spatter spray and then coating the spray with a powdered flux material. Alternatively, the powdered flux material can be electrostatically sprayed onto the coated metal sheet. |
