The invention provides a laser welding technology, and belongs to the technical field of laser welding. The laser welding technology comprises the steps that a molten pool is formed on a weldment by utilizing two focusing spots formed in the preset direction through a laser light beam penetrating through a lens assembly in a laser welding lens, the two focusing spots comprise the first focusing spot and the second focusing spot, the first focusing spot and the second focusing spot are linear spots or elliptical spots, the projections of the first focusing spot and the second focusing spot in the preset direction have preset angles, and the length of the molten pool is greater than the width of the molten pool. The welding technology has the good welding effect. 本发明提供了种激光焊接工艺，属于激光焊接技术领域。种激光焊接工艺，包括：利用激光光束透过激光焊接镜头中的透镜组件在预设方向形成的两个聚焦光斑在焊件上形成熔池，两个聚焦光斑包括第聚焦光斑和第二聚焦光斑，第聚焦光斑与第二聚焦光斑均为线性光斑或椭圆光斑，第聚焦光斑与第二聚焦光斑在预设方向的投影具有预设角度，熔池的长度大于宽度。该焊接工艺具有较好地焊接效果。
