GMAW welding process training for high neck flange of thin-walled tube of transmission tower
State Grid of China Technology, Ji’nan, Shandong 250000, China
In order to meet the increasing demand for transmission and improve the transmission and economic performance, the development of UHV power grid is the commanding heights of the global transmission technology competition in the future. with the development of welding manufacturing technology, a steel tower with steel tube and flange as main component has been invested in the transmission line. The welding process performance has become an important part of quality assurance for transmission line. In the manufacturing process, thin walled pipe and neck flange welding, because of reducing the pipe diameter and wall thickness, accordingly put forward some new difficulties for its welding process. According to the welding technology characteristics of thin-walled pipe and neck flange, the corresponding welding training process is worked out, and training for relevant employees is carried out, so as to achieve the purpose of controlling the welding process and improve the qualification rate of products at a time.
