Embodiment 2

[0041] It should be further explained that the angle steel used to manufacture the iron tower at present is hot-dip galvanized angle steel, the hot-dip galvanized angle steel has good strength, and has good corrosion resistance before the surface hot-dip galvanized layer is damaged, but once the surface hot-dip galvanized layer is corroded, the angle steel is easily corroded.

[0042] The traditional laser printing is to use the high heat characteristics of laser to oxidize and corrode part of the material on the surface of the object to print out the mark, and this printing mark scheme will oxidize the hot-dip galvanized layer on the surface of the angle steel when printing the hot-dip galvanized angle steel, thereby reducing the corrosion resistance of the angle steel, and for the angle steel used to manufacture the iron tower, the reduction of the corrosion resistance will seriously affect the service life of the iron tower.

[0043] Based on the above, the application further provides a hot-dip galvanized angle steel laser marking method based on the device disclosed in embodiment 1.

[0044] ​​Firstly, the angle steel is placed on the support strip 13, then the electromagnet on the bottom block 14 is turned on, so that the hot-dip galvanized angle steel becomes a magnet itself, then a layer of iron powder is evenly applied on the surface of the angle steel where the marking is needed, under the action of the electromagnet, the iron powder will be adsorbed on the surface of the angle steel, and the iron powder forms a printing layer on the surface of the angle steel, then the laser marking instrument 20 is turned on, and the laser is irradiated on the printing layer, and the iron powder irradiated by the laser is oxidized into magnetite and iron oxide due to high heat, and the magnetite and iron oxide generated by the laser irradiation will not volatilize due to the adsorption of the electromagnet, but will be adsorbed on the surface of the angle steel (i.e. on the hot-dip galvanized layer). At the same time, the hot-dip galvanizing at the laser irradiation position will undergo thermal melting due to the high heat of the laser during irradiation, and the magnetite and iron oxide generated by the laser irradiation will be bonded due to the adsorption of the electromagnet and the thermal melting of the hot-dip galvanizing, and after the printing is completed, the electromagnet stops working, and the magnetite and iron oxide will be bonded on the hot-dip galvanized layer, and the excess iron powder on the surface of the hot-dip galvanized layer is wiped off, thereby completing the entire marking operation. Such printing process will not corrode the hot-dip galvanized layer, and the printed mark will be blackish, and the blackish mark attached to the silver-white hot-dip galvanized surface will be more eye-catching, and the printing process will not affect the corrosion resistance of the angle steel.

[0045] The marking method provided by the embodiment is similar to the current 3D printing and belongs to additive printing, while the traditional laser marking belongs to subtractive printing. Embodiment 3
