| Abstract: | Laser beam welding can reduce the size of grain of high strength steel joints due to its rapid cooling resulting from its higher energy density and lower heat input. But there are some important problems in joint, such as solidification cracks, HAZ cracks and soften etc. In this paper, characteristics are described about laser beam welded high strength steel, Measures to avoid cracks and softening are introduced according to the latest researches in the world. |

| Keywords: | High strengthen steel Laser welding weldability welding cracks HAZ soften |
