TECHNICAL FIELD

[0002] Many high alloy materials such as stainless steel and nickel-based alloy are applied to material corrosion protection. However, in view of the relatively high cost of such materials under normal circumstances, it is a most practical method to surfacing a layer of alloy corrosion protection layer on cheap low-carbon steel or low-alloy steel bearing material. The surfacing of base material surface using a wire electrode submerged arc surfacing machine gives designers and manufacturers more freedom, which can be applied to different media corrosion scenarios by selecting various different base materials and welding materials, and is widely used in nuclear power, heavy load machines, engineering machinery, railway vehicles, coal machinery, wind power, steel structure, bridge, shipbuilding, power and other fields. The inner wall automatic surfacing machine can realize non-melting electrode TIG filling, FCAW wire electrode melting and melting electrode O2 flux cored wire surfacing process.
[0003] In the surfacing process, the welding electrode is generally kept stationary, and the cylinder is turned to complete welding to uniformly lay the welding material on the surface of the cylinder. Regardless of the process, the cylinder and the welding wire head are required to maintain a stable gap to facilitate the uniform laying of the welding material on the inner surface of the cylinder and maintain the spacing between the welds to ensure the quality of the weld.
[0004] However, after the welded cylinder is formed by rolling, ovality and edge angle are generated, and the cylinder will be axially offset after each turn due to uneven contact with the turning wheel during the turning process, which will affect the uniformity between the welds, causing uneven thickness of the welds and affecting the welding quality. After multi-pass welding, the cumulative offset is too large, which may cause the cylinder to move out of the turning frame and cause safety hazards. UTILITY MODEL CONTENTS
