Abstract

The invention relates to a large combined joist steel girder assembling automatic welding device and automatic welding method capable of achieving the purpose that no blind areas exist in the welding joint direction, and the device and method are used for automatic welding of large combined joist steel girders. A rack is fixed on one side of a rail, a walking trolley is connected with a rail sliding block which is matched with the rail in a sliding mode, a speed reducer is located on the walking trolley and is driven by a walking motor, the speed reducer drives a walking gear which is matched with the rack and drives the walking trolley to move on the rail, the walking trolley is connected with a y-axis adjusting mechanism which is connected with a z-axis adjusting mechanism, and the z-axis adjusting mechanism is connected with an x-axis adjusting mechanism which is connected to a welding gun clamp.

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.
