The application relates to a welding strip processing device, a battery string production line and a battery string. The welding strip processing device comprises a mounting assembly, a guide assembly and a surface treatment assembly. The guide assembly is rotationally connected to the mounting assembly, and is used for guiding the welding strip to be processed when the welding strip to be processed moves in a preset direction. The surface treatment assembly is arranged on the mounting assembly, and is used for etching the surface of the welding strip to be processed. When the welding strip for preparing a solar battery string is processed by the device, the guide assembly is used for guiding the welding strip to be processed when the welding strip to be processed moves in the preset direction, so that the direction of the welding strip to be processed is relatively accurate. In the subsequent welding process, the welding flux is no longer needed, the corrosion and damage of the welding flux to the string welding machine when the welding flux volatilizes and condenses on the string welding machine are reduced, and the welding flux that volatilizes and condenses can be prevented from adhering to the welding strip and the battery piece to corrode the welding strip and the battery piece.
