Problems solved by technology
Therefore, the efficiency is relatively low, and after the fixture is disassembled, the casing part 1 is prone to large deformation and welding diameter shrinkage. For the outer diameter D of the second horizontal part 133, the diameter shrinkage can even reach 0.8- 1mm, which also means that the design requirement of not less than 342mm cannot be met, which will lead to the scrapping of the casing part 1 and increase the maintenance cost

A casing part welding repair method and device, which includes the following steps, step A, providing a support ring, a tension ring, a drive disc and a pressure ring. An annular water tank is arranged in the support ring to clamp the parts of the casing. Step B, connect the waterway, keep the water body flowing in the water tank, and perform surfacing welding operation. After the welding is completed, take out the casing parts, and complete the welding repair of the casing parts. The welding and repairing method of casing parts provided by the invention can effectively control welding deformation, increase welding speed, and improve production efficiency. The present invention provides an apparatus for use in the above method.
Description
Technical field[0001]The present invention relates to the field of welding techniques, and more particularly to a method of welding the cartridge parts of an air engine, the present invention provides a device for the method.Background technique[0002]figure 1 Schematic diagram of the cross-sectional structural principle of a cartridge part of an aviation engine, seefigure 1 Distancefigure 1 The casing part 1 is welded from the first thin wall member 11, the second thin wall member 12, and the third thin wall member 13 connected from the inner to the inner order, and the third thin wall member 13 includes sequential settings. The first horizontal portion 131, the first connecting portion 132, and the second horizontal portion 133, the lower surface of the second horizontal portion 133, provided a downward first protruding portion 134.[0003]During the use of the aerospace engine, the upper surface of the second horizontal portion 133 of the third thin wall member 13 will be worn as a ...
