The utility model discloses a battery cell pre-welding clamp box and a welding device, and belongs to the technical field of battery cell assembly. The battery cell pre-welding clamp box comprises a clamp box body, the clamp box body comprises a pre-welding bottom support and a pre-welding top cover which are buckled up and down, and a containing cavity is formed in the clamp box body and used for containing a battery cell; the two electrode lug outlets are formed in the front wall surface of the clamp box body, and electrode lug pre-welding parts of the battery cells penetrate through the electrode lug outlets and extend out; the limiting boss is arranged on the front wall face of the clamp box body in a protruding mode, and the limiting boss extends by a set length relative to the front wall face of the clamp box body. In the process of using the battery cell pre-welding clamp box, the protruding end face of the limiting boss abuts against the welding base, so that the distance between the front wall face o
