The utility model discloses a laser welding gas protection device and use this protection device's laser welding device. Safety cover fixed on the welding tip is the tube -shape casing of a suit in the welding tip periphery, the internal face of safety cover and the outer peripheral face of welding tip enclose into the top and seal, bottom openings's annular gas distribution chamber, the bottom openings in gas distribution chamber is for encircleing at welding tip outlying annular opening, and the top in gas distribution chamber intercommunication aeration jet, in welding process, air feeder passes through the aeration jet and pours into into in to the safety cover behind the protection gas, protection gas can be under the chamber wall restraint in gas distribution chamber, the peripheral annular air current that encircles the solder joint and arrange that forms at the welding tip, also protect gas to encircle laser welding's welding in it exactly, so that the area of contact of protection gas and solder joint increase, the active area of protection gas has just also been increased.
