How the five steps of laser cleaning work（2）


  1. Strong and short explosive force means faster removal

Laser etching can be considered similar to carving stone with a hammer and chisel. You can hit the chisel several times with a small hammer, or apply more force with a larger hammer, reducing the number of blows required and increasing the removal speed. This idea is the same as laser cleaning. All in order to remove contaminants, the fiber laser cleaning system can use two different methods to remove a given layer. The laser beam is a continuous light wave or a pulse with a given repetition rate. Even if the results are almost the same, the removal rates of different methods will vary greatly. Removal speed: For a given surface area, the continuous and continuous pulse laser will increase the output power by putting the same energy into a short pulse. This is equivalent to using a larger hammer. The pulsed laser beam is more effective than the continuous laser beam, and the removal speed is faster. Short laser pulses clean surfaces faster, but ensure that the basic material does not overheat.

  1. No consumables and environmental protection

Since this cleaning method only uses a laser beam to evaporate the layer to be removed, there are few consumables. This is the beauty of lasers, which can be used with only one power plug. It is important that the laser does not use chemical products or solvents. This makes laser surface cleaning one of the safe solutions for rust removal and coating removal. Not only is there no chemical waste to be disposed of, but employees are completely safe when working near laser cleaners that meet international laser safety standards. Employees do not need personal protective equipment and do not have to deal with those annoying chemicals. That is, since laser cleaning will evaporate the material into smoke, you should install a smoke exhaust system near the laser to ensure that no paint, oil or dust particles are released into the air.

  1. Laser cleaning is very important for various industrial applications

Remove the burning rubber residues in the tire mold; Revitalize the old pipeline; Clean the nuclear power plant pipeline; Even larger projects, such as removing paint from rusty bridges and preparing welding surfaces, can benefit from industrial laser cleaning. This non-contact cleaning technology can be used in countless industrial applications. The only limitation is the ability to distinguish between materials to be removed and materials to be protected. At present, common laser cleaning applications include: welding pretreatment to remove rust and other contaminants in the welding area; Post welding treatment to remove aluminum and stainless steel oxides; Laser surface treatment, greatly improving paint adhesion; The oxides in special alloy ingots were removed by laser; Remove the coating immediately after the coating process to replace the mask of parts in the production line; Paint the parts scrapped due to paint defects.

3000W IPG fiber laser cutting machine work demonstration

Image
  This is a customized fiber laser cutting machine , its worktable size is 1500×6000mm, which is specially customized for users to process longer metal plates. The video shows the process of 3000W fiber laser cutting machine AKJ1560F cutting stainless steel plate and carbon steel plate with different thickness. The following introduces its features to you.   AKJ1560 fiber laser cutting machine is equipped with 3000W IPG fiber laser. The biggest feature of IPG fiber laser cutting machine is that it can cut highly reflective metal materials, such as copper, aluminum and other metals. It is well known that highly reflective metals have low absorption rates for laser light. When an ordinary laser cutting machine cuts aluminum, the light that cannot be absorbed by the aluminum is reflected on the lens and then transmitted to the fiber laser. In this case, not only the lens loss is large, but also the damage to the laser is large, which will seriously shorten the life of the fiber l...

Choosing a Fiber Laser Cutting Machine(3)

  CO2 laser generator is by far the most common fiber laser cutting machine choice for home and small businesses. They cost anywhere from a few hundred dollars to $10,000 and are capable of cutting wood and acrylic as well as thinner materials like cardboard. CO2 lasers are much larger than diode lasers, which means they require more tabletop or floor space. They also require more aggressive cooling than diode lasers, adding to the cost, size and complexity of the machine. Fiber Laser Generator is the most expensive option, often costing over $10,000 for entry-level cutters alone. However, they offer faster cutting speeds and are also capable of cutting metal. While fiber lasers are not an economical option for most hobbyist or small business users, they are the only option if you need to cut metal. What are the space requirements for a fiber laser cutting machine? Fiber laser cutting machines range in size from small desktops to professional-grade machines that require a lot of w...

How to make non-metal materials not dust during laser cutting（3）

  The design and functional requirements of non -metallic material laser cutting dust treatment purifier: 1. In the case of treating non -metallic materials to restore dust, the dust purification equipment has effective filtration functions and strong oily and anti -positive. 2. In order to handle odor dust, laser eliminate dust equipment must have carbon adsorption function, which is activated to effectively handle odor dust. 3. Because dust can change complex changes through factors such as other materials, density, temperature, and spatial characteristics. Therefore, it is necessary to retain the elimination of dust equipment to design the preliminary process of external accessories.
