Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a gas shielded welding anti-splash baffle. Background Art

[0002] Gas shielded welding is widely used in the field of industrial manufacturing. In the manufacture of metal products, including aviation, automobile, shipbuilding and other industries, gas shielded welding technology is used. Its welding joints have good sealing, strong corrosion resistance and high welding quality.

[0003] The principle of gas shielded welding is to cover the molten pool with a layer of inert gas during the welding process to prevent the molten pool from being oxidized and polluted by impurities such as oxygen and nitrogen in the air, so as to obtain high-quality welded joints. According to different types of gases, it can be divided into inert gas shielded welding and active gas shielded welding. The gas for inert gas shielded welding is generally argon, helium, etc. The use of inert gas protection can effectively prevent oxidation and is often used for welding stainless steel, copper and other materials; the gas for active gas shielded welding is generally carbon dioxide, oxygen, etc. In addition to the protective effect, it can also react with metal substances in the molten pool to generate beneficial gases, and is often used for welding carbon steel, low alloy steel, etc.

[0004] Gas shielded welding produces a lot of spatter. If the welding current, arc voltage and operating method are not correct, the spatter will be more serious and the slag will be difficult to remove, causing interference to the surrounding construction area. Summary of the invention

[0005] The utility model aims to provide a gas shielded welding anti-splash baffle to achieve the purpose of preventing gas shielded welding splash and reducing the splash range.

[0006] The utility model provides a gas shielded welding anti-splash baffle, which comprises a connection structure and is connected to a gooseneck of a welding gun through the connection structure; the connection structure comprises a connection plate, a baffle is arranged below the connection plate, and side plates are arranged on both sides of the baffle.

[0007] Furthermore, the connection structure is a clamp.

[0008] Furthermore, the connection structure includes an upper "J"-shaped plate and a lower "J"-shaped plate, one side of the upper "J"-shaped plate and the lower "J"-shaped plate are hinged, and through holes are arranged at corresponding positions on the other side; nuts are pre-welded at the through holes of the lower "J"-shaped plate, and the fixing nuts pass through the upper "J"-shaped plate and cooperate with the pre-welded nuts.

[0009] Furthermore, the baffle is in the shape of an isosceles trapezoid.

[0010] The utility model provides a gas shielded welding anti-splash baffle with three working states. When working in daily or temporary suspension, the baffle is perpendicular to the welding gun and can be used to assist in temporarily placing the welding gun. When working, the baffle is folded toward the nozzle direction to block the splash backwards, and the side plates block the splash on both sides. The upper opening is convenient for construction workers to observe. For special parts where the welding gun needs to be extended, the baffle can be folded toward the handle direction to avoid interference. The utility model achieves the purpose of preventing gas shielded welding splash and reducing the splash range, and has positive promotion significance at welding construction sites.
