Dry type laser cleaning device and method for nondestructive inspection liquid for aluminum alloy

Abstract

The invention discloses a dry type laser cleaning device and method for nondestructive inspection liquid for an aluminum alloy, and relates to the technical field of laser cleaning. The dry type lasercleaning device and method aim to solve the technical problem that in the prior art, the surface of a workpiece is prone to be damaged in the nondestructive inspection liquid clearing process. The dry type laser cleaning device comprises a controller, the controller is connected to a laser and a dust removal device, laser light emitted by the laser is irradiated on the surface of a workpiece through a laser cleaning head, the dust removal device recycles waste generated on the surface of the workpiece through a dust-absorbing bamboo joint pipe, the laser cleaning head comprises an isolator, one end of the isolator is connected to the laser, and the other end of the isolator is sequentially connected to a homogenizer, a Y galvanometer, an X galvanometer and an F lens. According to the device and the method, the laser is used for heating the nondestructive inspection liquid on the surface of the workpiece, so that the nondestructive inspection liquid can be instantly vaporized and evaporated, the damage to the workpiece is avoided, and the cleaning efficiency is high; the waste generated in the cleaning process can be synchronously recycled and treated in a concentrated mode, and the cleaning process is safe and environmentally-friendly; and various workpieces with complex surface structures can be cleaned, the number of the cleaning dead angles is small, and cleaning is thorough.

Description

technical field [0001] The invention belongs to the technical field of laser cleaning, and in particular relates to an aluminum alloy non-destructive flaw detection liquid dry-type laser cleaning device and method. Background technique [0002] Aluminum alloy workpieces generally require non-destructive testing after welding to determine whether there are obvious defects inside the weld. Non-destructive testing methods include radiographic testing, ultrasonic testing, magnetic particle testing, penetrant testing, eddy current testing, etc. Penetrant testing is one of the important non-destructive testing methods. After the flaw detection is finished, the non-destructive flaw detection fluid on the surface of the workpiece needs to be cleaned, otherwise it will affect the next process. The traditional mechanical grinding or chemical cleaning methods are easy to cause damage to the surface of the workpiece, and it is necessary to find a more efficient and environmentally frie...
