The utility model relates to the field of new energy equipment manufacturing, in particular to a longitudinal seam welding cantilever crane base structure which comprises a base flat plate fastened on the ground, an annular frame arranged on the base flat plate and a walking track arranged at the upper end of the annular frame. A plurality of inclined supporting columns are arranged on the outer side face of the annular frame in the length direction, one end of each inclined supporting column is connected with the ground, the inclined supporting columns, the annular frame and the ground form a triangular supporting structure, a crawling ladder is arranged on the side face of the annular frame in the width direction, the upper end of the crawling ladder is flush with the upper end of the annular frame, and the lower end of the crawling ladder is flush with the upper end of the annular frame. A guardrail is connected between the upper end of the crawling ladder and the annular frame, a grabbing handle is arranged on the guardrail, and a plane bedplate on which people stand is arranged at the position, close to the crawling ladder, of the upper end of the annular frame. The technical problems that an existing fixed welding arm frame is insufficient in machining flexibility and cannot adapt to production of workpieces of different sizes and shapes are solved.
