While the applications of lasers in cutting, drilling and welding are well known, their application in industrial cleaning is relatively new and has a wide, unexplored space.

The advantage of laser composite cleaning is that it combines the functions of continuous laser and pulsed laser at the same time to form a processing characteristic of 1+1>2.

With the rapid development of railway train technology, the speed of trains has been increased in recent years, and the performance requirements of various parts of the train have been correspondingly improved. An important part of wheelset maintenance is the ultrasonic inspection of axles and wheels to determine whether there are cracks inside the axles and wheels.

Laser cleaning technology uses nanosecond or picosecond pulse lasers to irradiate the surface of the workpiece to be cleaned, so that the surface of the workpiece absorbs the focused laser energy in an instant, forming a rapidly expanding plasma (a highly ionized unstable gas), making it Surface oil stains, rust spots, dust residues, coatings, oxide layers or film layers are vaporized or peeled off, so as to efficiently remove surface attachments.

Ships are vehicles that can navigate or berth in waters for transportation or operations, and have different technical performance, equipment, and structural types according to different usage requirements.In the course of nautical transportation, due to the long-term erosion of high temperature, high humidity, high salt and sea water on the hull, it needs to be returned to the factory for maintenance, and the overall surface of the hull is depainted and painted twice.

Laser cleaning is an emerging material surface cleaning treatment technology that can replace traditional pickling, sandblasting and high-pressure water gun cleaning. The laser cleaning machine adopts a portable cleaning head and a fiber laser.

Laser cleaning can be used not only to clean organic pollutants, but also to clean inorganic substances, including metal rust, metal particles, dust, etc. Here are some practical applications. These technologies are very mature and widely used.

Some people think that laser cleaning does not belong to laser processing technology. others think, Laser cleaning is the same as laser cutting, marking, welding, drilling and other processes.
