Welding equipment and battery production line

The utility model relates to the technical field of laser welding, and particularly discloses welding equipment and a battery production line, the welding equipment comprises a welding auxiliary component, and the welding auxiliary component is provided with a laser channel used for allowing laser to pass through during laser welding; the blowing channel forms a plurality of blowing ports in the inner wall of the laser channel, and the plurality of blowing ports are sequentially arranged at intervals in the circumferential direction of the laser channel; and the exhaust channel is communicated with the laser channel. According to the welding device, the protective gas blown out of the gas blowing channel is more uniform, smoke dust in the welding work area and the laser channel can be dispersed and exhausted through the exhaust channel, the probability that the smoke dust is gathered and detained in the welding work area and the laser channel is reduced, poor pseudo soldering is eliminated, and therefore the
