Embodiment 1
[0041] The pretreatment process of the steel surface of the ship in this embodiment adopts the crawling robot described in the first aspect of the present invention.
[0042] In this embodiment, the wavelength of the fiber laser 1 is 1064nm, the crawling robot is placed on the surface of the ship steel that needs to be cleaned, and the focal length of the fiber laser 1 is adjusted so that the surface of the ship steel that needs to be cleaned is placed at the laser out-of-focus plane position. Impurities on the surface of ship steel are oxide scales, old coatings, oil stains, welding slag, dust and other sundries retained by the steel products; The distribution is relatively uniform, and when processing the surface of ship steel, if the laser energy is too concentrated, it is easy to damage the surface of the substrate, and a new oxide layer will be generated, and the surface roughness will be very low.
[0043] The cleaning process is as follows: simply clean the surface of t...
Embodiment 2
[0046] A pretreatment process for the surface of ship steel in this embodiment uses the crawling robot described in the first aspect of the present invention.
[0047] In this embodiment, the wavelength of the fiber laser 1 is 1064nm, the crawling robot is placed on the surface of the ship steel that needs to be cleaned, and the focal length of the fiber laser 1 is adjusted so that the surface of the ship steel that needs to be cleaned is placed at the laser out-of-focus plane position. Impurities on the surface of ship steel are oxide scales, old coatings, oil stains, welding slag, dust and other sundries left by the steel from the factory; the position of the laser from the focal plane is negative 10mm from the focal plane, which is located below the focal plane, so that the laser spot power density The distribution is relatively uniform, and when processing the surface of ship steel, if the laser energy is too concentrated, it is easy to damage the surface of the substrate, ...
