Parts and equipment made of metal may produce an oxide layer during production or use. For example, a layer of oxide layer will be formed on the surface of rail steel after forging and hot rolling. For subsequent processing or use, the oxide layer needs to be treated. Clean up. Today we will introduce the oxide layer laser cleaning machine.
The oxide layer is a layer of dense oxide film formed on the surface of the metal meeting the air to prevent the metal from continuing to react with the air.
After metal welding, an oxide layer will form on the welding surface, especially at the weld. These oxide layers will seriously affect the use and appearance of the product. Conventional methods for removing the oxide layer include grinding and pickling passivation. Grinding to remove the oxide layer will damage the surface of the metal product, and the high temperature during grinding will cause stress deformation of the thin product. Pickling and passivation to remove the oxide layer requires the use of chemicals such as pickling solutions and passivation pastes that have a great impact on the environment. Products after pickling also need to consume a large amount of water to clean the remaining acidic substances. The recycling of these waste waters increases the processing cost of the enterprise.
Cleaning the metal oxide layer with laser has the advantages of fast speed, no damage to the substrate, no need for cleaning solvents, no pollutant discharge, and automatic cleaning. It is a supplement and improvement of traditional cleaning methods and can meet the unsatisfactory occasions of conventional cleaning. Before metal welding, laser cleaning is used to remove the oily grease oxide layer in the welding area, which is helpful to ensure the welding quality. After metal welding, cleaning the weld oxide layer with laser can not only facilitate the inspection of welding quality, but also eliminate the influence of metal product weld oxide layer on use.
Oxide layers are often formed on the surface of steel wires and aluminum alloys, which are usually removed by polishing or laser removal. Polishing to remove the oxide layer will generate a lot of dust, which will not only endanger the health of users, but may also cause explosions. The way of laser removal can reduce the generation of dust, but the efficiency of existing laser removal equipment is low, and the machine is relatively heavy.
In order to solve the cleaning problem of various metal oxide layers, the handheld laser cleaning machine of Legent Laser has the following advantages:
1. It adopts an integrated structure design, and can be equipped with MOPA pulsed fiber laser or flat-top pulsed fiber laser according to requirements;
2. The multifunctional laser cleaning machine control system configured by Legent can easily connect to the automatic processing systems of various industries;
3. Built-in smoke and dust purification system to achieve low pollution emissions in line with national environmental protection requirements;
4. Equipped with an elastic weight reducer, which can be adjusted freely in three directions, reducing the operating weight and making cleaning more labor-saving;
5. Optional dual temperature and dual control water cooling system can effectively guarantee the continuous and stable operation of the laser and cleaning head for a long time;
6. There are many applicable scenarios and the cleaning is cleaner.
Mainly used in laser cleaning and surface laser pretreatment of precision molds, metal products, shipbuilding, construction engineering, automobiles, sheet metal/spraying and other metal surfaces.
