A welding blow protection device for the open laser vibration lens of the utility model includes a vibrating mirror and a protective gas cover set under the vibrating mirror. The protective gas cover is connected with a vibrating mirror by the mounting bracket, and an open opening is protected on the upper and lower ends of the gas cover, and the circumference of the protective gas shield is enclosed in an oxygen free area welding inner cavity on the surface of the workpiece. At least one air hole is provided in the side of the gas shield, and the welding area of the inner cavity surrounding the vibrating mirror is welded, and the inlet air hole is used for the guiding protection gas to be filled with the inner cavity of the welding, so that the welding inner cavity is isolated from the outside air. Compared with the existing technology, the welding blowout protection device of the laser vibration lens of the utility model is provided with a protective gas cover under the vibrating mirror, and the protective gas is input to the gas shield into the air hole to fill the welding inner cavity, so that the workpiece is welded in the welding inner cavity which is isolated from the outside air, and the laser radiation is prevented. The metal pool formed on the surface of the workpiece is oxidized to reduce subsequent processing and improve production efficiency.
