The utility model discloses an accurate positioning device for a welding seam in a stainless steel cold rolling line, which comprises a steel belt and a tension roller group driven by a tension roller driving mechanism to rotate, the steel belt is wound on the tension roller group, a welding station and a crescent shear station are arranged on a conveying path of the steel belt, and a positioning through hole is formed in the steel belt; a photoelectric sensor is arranged between the welding station and the crescent shear station; a rotary sensor is further arranged on one tension roller in the tension roller set, and the rotary sensor, the photoelectric sensor and the tension roller driving mechanism are all in communication connection with a controller. According to the accurate positioning device for the welding seam in the stainless steel cold rolling line, the walking distance of the steel belt is determined according to the in-place information of the positioning through hole sensed by the photoelectric
