    • A method of laser welding structures having different steel grades together. The method includes providing a first structure made from a first steel grade and composition and providing a second structure made from a second steel grade composition. The first structure is positioned adjacent the second structure to create a weld zone area wherein at least a portion of the first structure overlaps at least a portion of the second structure. A filler material is selected that has a composition that will create a weld joint between the first structure, the second structure and the filler material such that the weld joint has a predetermined microstructure. The filler material is positioned adjacent the weld zone area. A laser beam is directed at the weld zone area to create a weld joint between the first structure, the second structure and the filler material wherein the weld joint has a predetermined microstructure.
    • 一种具有不同钢种的激光焊接结构的方法。 该方法包括提供由第一钢种和组合物制成的第一结构,并提供由第二钢级组合物制成的第二结构。 第一结构定位成邻近第二结构以产生焊接区域区域,其中第一结构的至少一部分与第二结构的至少一部分重叠。 选择具有将在第一结构,第二结构和填充材料之间形成焊接接头以使得焊接接头具有预定微结构的组合物的填充材料。 填充材料位于焊接区域附近。 激光束被引导到焊接区域,以在第一结构,第二结构和填充材料之间形成焊接接头,其中焊接接头具有预定的微结构。
