Other AbstractThe present utility model discloses a noble gas protection device for laser beam welding. The noble gas protection device consists of two symmetrical sections, each section comprises a base plate which is provided with a concave platform and an upper cover board which is positioned on the concave platform, the bottom of the concave platform is opened with an air storage groove with one end havingan air inflation inlet and the other end being closed, and the air storage groove and the upper cover board form a closed air storage cabinet a side of the upper cover board adjacent to a welding line is provided with a chamfer angle, and air outlet holes communicated with the air storage cabinet are distributed evenly along the whole length on the plane of the chamfer angle. The utility model ischaracterized in that noble gas for protection is spayed out evenly from the air outlet holes along the whole length of the welding line to protect the back of the welding line, improving the protection effect because the air outlet holes are positioned at the side of the device, the damage of the air outlet holes from lasers can be avoided the device is also provided with a welding slag discharging groove, being good for the discharging of welding slag on the back side when laser beam welding is performed.
