Beschreibung
Zusammenfassung:	The invention discloses a turbine working blade special-shaped air film hole laser repairing method which comprises the following steps: determining the hole position of a round straight hole in a special-shaped air film hole, collecting hole position coordinate data, correcting the deviation of position coordinates collected during hole position analysis, pasting an industrial adhesive tape on a special-shaped hole repairing part, and measuring a Z-axis coordinate point. According to the method, camera capture errors are eliminated, correct position coordinates of the special-shaped air film hole of the part are guaranteed, the repaired part of the special-shaped air film hole is coated with ceramic powder, and a coating is prevented from being polluted in the repairing process; first holes in each row of holes are selected for trial machining, the correctness of the special-shaped hole information collected during hole site analysis and the shape of the repaired special-shaped holes is mainly checked, and m
