摘要：

Laser welding, which has many advantages such as high-speed process, deep penetration, narrow weld width, remote control etc., has been industrial applied for several industries. The formation of molten pool, and the mechanism of spatters generation have not been sufficiently investigated. In this study, we performed bead-on-plate welding tests on SS304 plates using disk laser by changing atmosphere pressure. The laser welding was observed in real time using the glass transmission method, and the shape of the molten pool was observed. As a result, it was found that the length of the molten pool was a factor for spatter suppression.
