Construction site automatic welding method for super-large-section steel structure bridge tower

The invention discloses an automatic welding method for a super-large-section steel structure bridge tower on a construction site. The super-large-section steel structure bridge tower comprises a lower-layer tower section, a middle tower section and an upper-layer tower section. The lower-layer tower section comprises a steel-concrete combined block body, a pressure-bearing plate block body, a side block body and a core concrete block body; each middle tower section comprises a side block body and a core concrete block body; the upper-layer tower section comprises a tower crown block body. Tower sections of the bridge tower with the super-large section and the steel structure are all in all-welded connection, longitudinal butt welding seams between blocks of the same section need to be welded after high-altitude hoisting of a bridge site, and welding of transverse butt welding seams between the tower sections also needs to be completed. According to the construction site automatic welding method suitable for
