摘要：

In this paper, boron alloy steel EN 10 292 TL4225 is selected for the study. The laser spot welding process, one kinds of advanced jointing technology, is used. We get the perfect welded joints of ultra-high strength stamping parts gained by hot stamping process through using the optimum welding parameter. The welding performance of the welded joints, such as the metallography phase is tested, the tension strength is tested, and the microstructure of the fracture visage is analyzed by scanning electron microscope. The test results showed that the welded joints have good mechanical performance by using laser spot welding process, and the mechanical performance meet the actual need of product well.
