Joined plate welding platform

The invention provides a joined plate welding platform, and relates to the field of joined plate welding. The joined plate welding platform comprises a first frame, a welding mechanism and an edge milling mechanism, and further comprises a second frame arranged with the first frame side by side; the first frame and the second frame are provided with clamping structures for mounting and positioningsteel plates; a milling and welding channel is reserved between the first frame and the second frame; the welding mechanism and the edge milling mechanism are movably mounted on the side, corresponding to the milling and welding channel, of the first frame; the moving directions of the welding mechanism and the edge milling mechanism extend in the length direction of the milling and welding channel; the second frame and the first frame are assembled in a relative translation mode; and the second frame extends in a direction perpendicular to the horizontal direction of the milling and weldingchannel relative to the tr
