[0002] A flare tower is a device that treats waste gas by high-altitude open-air combustion. It is also an important equipment in offshore oil and gas production systems. Generally, safety and stability need to be considered in the construction of a flare tower, especially the welding and fixation of the flare tower base. Most flare towers are made of circular columns spliced ​​by flanges, and the corresponding circular columns of the flare tower base are also circular. During actual use, the flare tower is partially increased in height as needed, and these locally increased circular columns are usually installed by welding.

[0003] The base of the flare tower is usually connected by manual welding. Since the welding of circular columns requires turning in circles, manual welding is inconvenient to operate, and there is no limit guide during welding, resulting in the welding quality cannot be guaranteed. The existing automatic welding equipment is not suitable for the welding of circular columns of various pipe diameters and has limitations. Utility Model Content
