The utility model provides a novel gas welding nozzle, and belongs to a part on a welding tool. The novel welding gas nozzle is provided with a welding nozzle body, wherein one side surface of the welding nozzle body is provided with a baffle plate, the other side of the welding nozzle body is provided with an air outlet hole, and mixed gas holes in the baffle plate are communicated with an inner cavity of the welding nozzle body; and the middle of the baffle plate is provided with a column body, the mixed gas holes are positioned in the baffle plate which is arranged outside of the column body, and the side surface of the baffle plate is provided with a sealed inclined surface. The gas welding nozzle is installed on a welding gun, and the column body can block a high-pressure oxygen inlet; when a misoperation is generated, high-pressure oxygen is prevented from entering the inner cavity of the welding nozzle body, meanwhile, the high-pressure oxygen is prevented from entering an acetylene bottle, so that the
