Description

technical field [0001] The invention relates to an automatic welding device and an automatic welding method for the assembly of large composite girder steel main girders, which can realize no blind area in the welding seam direction and is used for automatic welding of large composite girder steel main girders, and belongs to the field of special welding equipment manufacturing. Background technique [0002] In recent years, large-scale composite beams have been widely used due to their excellent comprehensive performance, and the ring joints between segments of the steel main girder assembly are one of the most important welds, and the number is relatively large. At present, manual welding is mostly used for butt joints of the roof, bottom and web between segments. The welding quality is greatly affected by personal emotions, welding skills, physical conditions, etc., and the consistency and reliability of the welding quality cannot be guaranteed.
