Welding fixing device

The utility model relates to a welding fixing device. The welding fixing device comprises a grounding base, a conductive piece, a first clamping piece and a second clamping piece. The grounding base is used for grounding. The conductive piece is connected with the grounding base. The first clamping piece is arranged on one side of the conductive piece. The second clamping piece is arranged on the other side of the conductive piece, the second clamping piece and the first clamping piece are magnetically attracted, and a clamping position used for clamping a workpiece to be welded is formed between the second clamping piece and the conductive piece. According to the welding fixing device, displacement of the workpiece to be welded in the welding process is avoided, the possibility of welding spot deviation caused by shaking of the workpiece to be welded is reduced, the welding efficiency is improved, stable current conveying is guaranteed, and therefore stable arcing of the workpiece to be welded in the welding
