Zusammenfassung:	The invention discloses a weld joint positioning method. The weld joint positioning method includes the steps that: a weld joint positioning image which comprises a first structural light line, a second structural light line and a third structural light line is obtained, and the first structural light line, the second structural light line and the third structural light line are parallel to one another; cross points of the first structural light line and a weld joint, the second structural light line and the weld joint, as well as the third structural light line and the weld joint are determined correspondingly according to the weld joint positioning image and first coordinates, second coordinates, and third coordinates are obtained; a first coordinate difference of the first coordinate and a first coordinate in the previous frame of weld joint positioning image is obtained, and a second coordinate difference of the second coordinate and a second coordinate in the previous weld joint positioning image is obta
