Laser cleaning systems have long been used in the aviation industry in Europe. The surface of the aircraft needs to be repainted after a certain period of time, but the original old paint needs to be completely removed before painting. Traditional mechanical paint removal methods are likely to cause damage to the metal surface of the aircraft and bring hidden dangers to safe flight. If multiple laser cleaning systems are used, the paint on the surface of an A320 Airbus can be completely removed within two days without damaging the metal surface.
