Claims

[Scope of utility model registration request]

The object to be welded is moved along the welding line by a guide rail attached to the seam welding machine body, and a rotary table that engages with the guide rail and is movably and rotatably supported by the seam welding machine body in a horizontal plane. In the welding object guiding device for a seam welding machine, the welding object is guided by an upper electrode and a lower electrode, the welding object is sandwiched between an upper electrode and a lower electrode, and the welding is performed while applying pressure and electricity by rotating both electrodes. A balance cylinder device is provided between the seam welding machine main body and the rotary table, and the balance cylinder device is provided with a rotational assisting force that generates a force smaller than the moving force of the rotary table in the rotational direction of the rotary table. A biasing circuit is switchably connected to a force biasing circuit in a counter-progressing direction that generates a force smaller than the force generated by the rotational auxiliary force biasing circuit in a direction opposite to the traveling direction of the workpiece. A workpiece guidance device for seam welding machines.
