The technical scheme is as follows: the gas shielded welding nozzle of the utility model comprises a welding gun seat, a welding gun sleeve, a gas splitter, a laser, a focusing lens, a conductive nozzle and a nozzle; the nozzle is in butt joint with the welding gun sleeve to form a cavity, and the welding gun seat, the laser, the focusing lens and the contact tube are sequentially connected in the cavity along the axial direction; the rear half section of the gas splitter is arranged between the welding gun seat and the welding gun sleeve, the front end of the gas splitter is connected with the outer wall of the conductive nozzle, the front half section of the gas splitter is provided with a gas distribution hole, and the welding gun seat is provided with a vent hole communicated with the gas distribution hole; and a flow guide valve is arranged between the conductive nozzle and the nozzle.
Further perfecting the technical scheme, the gas distribution holes are two groups and are distributed at intervals along the front half section of the gas splitter, and each group of gas distribution holes are 8 through holes which are uniformly distributed along the radial direction of the gas splitter.
Furthermore, the vent hole is 8 through holes which are uniformly distributed along the radial direction of the welding gun seat.
Furthermore, the number of the diversion valves is two, and the diversion valves are provided with arc-shaped diversion holes.
Furthermore, the nozzle is cylindrical, and the front end of the contact tube is provided with a helical blade.
Has the advantages that: compared with the prior art, the utility model has the advantages that: the utility model discloses a setting of gas shunt, welder seat air vent, diverter valve has changed the direction and the effect of air current, guarantees that air current size, direction are as even as possible and unanimous, forms the gas curtain of all-round protection, has guaranteed that gas shunt is smooth and easy, prevents that impurity from blockking up gas passage, and the protection is respond well, can effectively prolong welder's operating time.
The nozzle and the spiral blade at the front end of the contact tube form a double-layer spiral structure, and protective gas enters the nozzle and then is spirally sprayed out under the action of the spiral blade, so that the stirring effect is achieved, and the performance of a welded joint is improved.
