Method and device for achieving thin-wall part back face induced localized electro-deposition through laser irradiation

The invention discloses a method and device for achieving induced localized electro-deposition on the back face of a thin-wall part through laser irradiation, and relates to the field of non-traditional machining. The tool anode is arranged on the back face of the to-be-repaired part, a certain gap is kept between the tool anode and the to-be-repaired part, a laser beam is focused on the outer surface of the to-be-repaired part, and localized repair of the back face is achieved. Aiming at the problem that inner wall coatings of tubular parts, box parts and the like fall off, lose efficacy and are difficult to repair, the characteristic of high heat conductivity of the workpiece is utilized, the laser heat effect and electrochemical deposition are cooperated, localized coating repair of the back surface of the workpiece is realized, electrodeposition reaction does not occur in other areas which do not need to be repaired, the operation process is simple, the plating solution cost is greatly saved, and the work
