[0004] The steam drum (also known as the drum) is the most important pressure component in the natural circulation boiler. It is mainly used in the medium-pressure and high-pressure subcritical boilers for power production. The steam drum in the prior art generally includes a cylindrical shell and is arranged on a cylindrical shell. Several connecting pipes on the cylindrical shell, the connecting pipes are welded with the cylindrical shell, and the connecting pipes located at both ends of the same diameter line of the cylindrical shell are required to ensure a certain degree of concentricity, but at present, when workers weld the connecting pipes, they do not rely on any Welding tooling, weld the connecting pipe to the cylindrical shell directly based on experience, so that it is difficult to ensure the concentricity of the connecting pipes located at both ends of the same diameter line of the cylindrical shell

The invention relates to a welding tool capable of ensuring concentricity of workpieces. The welding tool comprises a lengthwise steel pipe. One end of the lengthwise steel pipe is provided with a first supporting mechanism and a second supporting mechanism. The other end of the lengthwise steel pipe is provided with a third supporting mechanism and a fourth supporting mechanism. The first supporting mechanism comprises a first connection pipe and a first supporting plate. The first connection pipe and the lengthwise steel pipe are welded. The first supporting plate and the first connection pipe are welded. The structures of the second supporting mechanism, the third supporting mechanism and the fourth supporting mechanism are identical to that of the first supporting mechanism. By adopting the welding tool for welding operation, concentricity of connected pipes is greatly improved.
Description
[0001] 【Technical field】 [0002] The invention relates to a tool, in particular to a welding tool which can ensure the concentricity of workpieces. [0003] 【Background technique】 [0004] The steam drum (also known as the drum) is the most important pressure component in the natural circulation boiler. It is mainly used in the medium-pressure and high-pressure subcritical boilers for power production. The steam drum in the prior art generally includes a cylindrical shell and is arranged on a cylindrical shell. Several connecting pipes on the cylindrical shell, the connecting pipes are welded with the cylindrical shell, and the connecting pipes located at both ends of the same diameter line of the cylindrical shell are required to ensure a certain degree of concentricity, but at present, when workers weld the connecting pipes, they do not rely on any Welding tooling, directly weld the connecting pipe to the cylindrical shell according to experience, so it is difficult to ensur...
