The utility model relates to a protection device for metal welding engineering, which comprises a welding gun, a fixed outer plate is fixedly arranged outside the welding gun, a welding protection mechanism is arranged outside the welding gun, and the welding protection mechanism comprises a protection cover fixedly arranged outside the fixed outer plate. And a gas collecting box arranged outside the welding gun in a sleeving manner is fixedly mounted in the protective cover. According to the protection device for the metal welding project, the rolling wheels are pressed on metal needing to be welded, the rolling wheels are extruded and jacked upwards to push a piston out of the interior of a gas intercepting ring, and at the moment, protection gas protected in a protection gas guide pipe flows into a gas collecting box and flows out of the bottom of a gas outlet cylinder to conduct welding protection on a welding gun; when the device is lifted up, the spring loses pressure and expands, the piston is pushed i
