Other AbstractThe invention discloses a welding line back side inert gas protection device for laser welding. The protection device for realizing the method consists of two symmetrical parts, wherein each part comprises a pedestal and an upper cover board; the pedestal is provided with a boss; the upper cover board is arranged on the boss; a gas storing tank of which one end is provided with an inflation inlet and the other end is closed is formed at the bottom of the boss; the gas storing tank and the upper cover board form a closed gas storing cabin; the edge of the upper cover board, which is close to the welding line, is chamfered; and gas outlet holes which are communicated with the gas storing cabin are uniformly distributed on the chamfered face along the overall length. The backside inert gas protection method and the back side inert gas protection device for the laser welding have the advantages that: protective gas is uniformly sprayed along the overall length of the welding line from the gas outlet holes on the side of the device to protect the back side of the welding line, so that protection effect is improved; the gas outlet holes are positioned on the side of the device, so that the damage of laser to the gas outlet holes is avoided; and a slag spout is formed in the middle of the device, so that the removal of welding slag on the back side in the process of the laser welding is facilitated.
