With the rapid development of China's energy industry, marine energy exploitation has become an important part of China's oil supply, which has adjusted China's energy structure. Therefore, in the exploitation of offshore oil such as islands, spherical tank engineering has been greatly affected, which requires us to improve the automatic welding technology of wall climbing robot. Through the automatic welding technology of climbing wall welding robot, we can improve the welding quality and efficiency of spherical tank, which will improve the all position welding technology of spherical tank in China. Therefore, the disadvantages of low efficiency of traditional electrode arc welding process can't meet the needs of offshore oil storage and transportation, which requires us to improve the automatic welding technology of spherical tank wall climbing welding robot, which has become the dream of Offshore Petrochemical construction. Firstly, this paper analyzes the application of spherical tank welding robot. Then, the fusion welding forming model based on BP neural network is studied. Finally, this paper analyzes the key technology trend in the future.
