The utility model provides a welding shielding gas nozzle. The welding shielding gas nozzle comprises a gas spraying pipe and a scraping brush cleaning structure rotationally installed on the gas spraying pipe. A scraping and brushing plate is arranged on the scraping and brushing cleaning structure, extends into the air spraying pipe from the air outlet end of the air spraying pipe, and abuts against the inner wall of the air spraying pipe to slide; when the scraping brush cleaning structure is rotated, the interior of the air outlet of the air spraying pipe can be cleaned; the nozzle is novel in structure, the air outlet part of the nozzle can be conveniently cleaned, the problem of blockage caused by caking of chips adhered to the interior is effectively prevented, and smooth air injection is maintained. 本实用新型提供了一种焊接保护气喷嘴，包括喷气管，转动安装在喷气管上的刮刷清理结构；刮刷清理结构上设有刮刷板，刮刷板从喷气管的出气端伸入喷气管内部，刮刷板抵持喷气管的内壁滑动；转动刮刷清理结构时可对喷气管的出气口内部进行清理；其结构新颖，可方便对喷嘴的出气口部位进行清理，有效防止内部粘附碎屑结块而导致堵塞问题，维持喷气的顺畅。
