Beschreibung
Zusammenfassung:	A laser welding copper nozzle, a laser welding auxiliary device, and a laser welding apparatus. The laser welding copper nozzle has: air inlets (1) used for communication with air inlet channels (2), so that during laser welding, an air blowing apparatus blows air to the air inlets (1) through the air inlet channels (2); air outlets (3) used for communication with air extraction channels (4), so that during the laser welding, a suctioning apparatus extracts air from the air outlets (3) through the air extraction channels (4), the axis of each air inlet (1) and the axis of the corresponding air outlet (3) being on a same straight line, and a laser channel for allowing laser light to pass through during the laser welding being formed between the air inlet (1) and the air outlet (3). The axis of the air inlet (1) and the axis of the air outlet (3) are on the same straight line, so that shielding gas can be independently controlled when flowing from the air inlet (1) to the air outlet (3), such that the shielding
