Description

Technical Field

[0001] This invention relates to the field of mechanical technology, specifically to a welded structure for cast steel components of a steel pipe tower. Background Technology

[0002] Cast steel parts are mechanical components made of cast steel, possessing higher strength than cast iron, and fall under the category of mechanical engineering terminology. Their advantages include high design flexibility, allowing for the fabrication of complex structures through core-assembly processes; strong adaptability to metallurgical manufacturing, with properties adjustable through heat treatment; and a weight range from tens of grams to hundreds of tons. However, they also have defects such as uneven microstructure, rough surface, and susceptibility to porosity. Production requires electric furnace melting, followed by stress relief through annealing or normalizing treatments. The casting process necessitates controlling the fluidity and shrinkage rate of the molten steel. The traditional steel pipe tower casting welding stage is quite difficult. Moreover, there is no corresponding positioning welding for the steel components to provide for the positioning soldering of the steel pipes. Furthermore, there is no actual structure to assist personnel in the specific positioning soldering of the steel pipe structure during the steel component welding stage of the steel pipe tower. This results in poor welding precision of the steel pipe tower castings and poor connection capability of the joints. It is easy to cause the subsequent soldering positioning of the steel pipe tower castings to lack actual structural support. Summary of the Invention
