Abstract

This invention provides an arc welding device for butt joints of metal shells. It relates to the technical field of metal welding equipment. The arc welding device for butt joints of metal shells includes two mounting frames, each with four support legs fixedly mounted on its bottom. Each mounting frame is equipped with a clamping assembly that firmly holds the two metal shells to be welded, ensuring smooth welding. The clamping assemblies are adjustable to accommodate metal shells of different specifications within a certain range. An adjustment assembly is located below each mounting frame, capable of adjusting the height of the welding torch and welding rod (mentioned below), enabling longitudinal welding of the butt joint between the two metal shells. A feeding assembly is located on one side of the adjustment assembly. This invention has the advantages of precise centering positioning capability, a wide adaptive clamping range, a multi-dimensional adjustable welding mechanism, and support for dual-mode electrode movement.
