The invention discloses a top cover cross beam clamp, a body-in-white main splicing clamp assembly and a welding positioning method.The top cover cross beam clamp comprises a bottom frame, a positioning clamping mechanism set, a bottom frame positioning mechanism and a hoisting mechanism, the bottom frame comprises an overall frame, and the overall frame comprises cross beams and longitudinal beams; each positioning and clamping mechanism set comprises a first positioning and connecting assembly and a second positioning and connecting assembly, the first positioning and connecting assemblies and the second positioning and connecting assemblies are oppositely fixed to the longitudinal beams, the bottom frame positioning mechanisms are arranged at the corners of the bottom frame, and the lifting mechanisms are evenly arranged on the bottom frame. The clamp is simple in structure, one-time positioning connection of a plurality of top cover cross beams can be easily completed, the clamp and the top cover cross beams are lifted together through the lifting mechanism, the chassis positioning mechanism and the body-in-white main splicing clamp are accurately positioned, welding is conducted after the top cover cross beams and the upper portion of the body-in-white side wall are accurately positioned, welding is easy, and welding efficiency is high. Spot welding space is sufficient, precision is high, after welding, the clamp is loosened to lift and move out, and operation is easy.
