Novel double-end automatic welding machine

The invention discloses a novel double-end automatic welding machine which comprises a rack, a driving module, a supporting frame module, an electric adjusting seat module, a welding gun module and a plc, the driving module comprises an electric lifting seat, a driving seat and a driving mechanism, and the driving module comprises an electric lifting seat, a driving seat and a driving mechanism. The driving seat is installed in the middle of the supporting frame in a matched mode through the electric lifting seat, the plc is in control connection with the electric lifting seat, a driving friction roller and a driven friction roller are installed at the top end of the driving seat in parallel at intervals in the longitudinal direction, and the driving friction roller is in transmission connection with the driving mechanism. The plc can drive the driving friction roller to rotate at a constant speed through a driving mechanism; the horizontal welding device is unique in structure and ingenious in design, the pr
