The Shenzhen-Zhongshan cross-river channel was completed and opened on June 30. Xi Jinping, General Secretary of the CPC Central Committee, President of the State and Chairman of the Central Military Commission, sent a congratulatory letter, expressing warm congratulations and sincere greetings to all comrades involved in the planning and construction.
The Shenzhen-Zhongshan Channel has eight lanes in both directions, and the diameter of the immersed tube is wider than that of the Hong Kong-Zhuhai-Macao Bridge. Each immersed tube weighs 9,000 tons. If manual welding is used, more than 1,000 welding workers are needed for a steel shell of an immersed tube, and the construction period is as long as 12 months. It is obviously impossible to complete the task on time if it is all manual. Therefore, the use of efficient robot welding has become an inevitable option.
Xinxiang Heguang Technology Co., Ltd. has developed a seamless flux-cored welding wire for robot high-speed welding for Guangzhou Shipyard International Co., Ltd., which has been fully applied in the flat longitudinal bone welding line, sheet robot welding production line, TB robot production line, and thin plate welding robot production line. With its stable ultra-low diffusible hydrogen content, it effectively reduces the generation of hydrogen cracks, and the excellent anti-pore ability of paint surface welding makes the weld rarely have pores. The high-speed, smooth and stable wire feeding performance makes the entire welding work smoother, and the ultra-low wear of the conductive nozzle reduces the number of replacements during the welding process, greatly improving production efficiency.
With the continuous advancement of my country's intelligent manufacturing, the scenes of large-scale special machine automated welding and robot welding will be more widely used. Our ultra-low hydrogen seamless flux-cored welding wire of Heguang Technology Co., Ltd. will continue to help China's intelligent manufacturing develop rapidly with its unique special technology.
