Selective laser cleaning
Local cleaning of surface areas is another advantage of the F-Clean laser system, which extends the scope of the device. In our article we tell you more about what selective treatment tasks can be solved with laser equipment.
Preparing for welding
Creating a quality welded joint is the most important step in the production of any metal structure. Small items sometimes require more preparatory effort than larger items. The quality of the future weld is directly dependent on the thoroughness of the pretreatment. Laser complex F-Clean can with the same accuracy perform pre-treatment of surface of any size: remove traces of dirt, rust, oxide films, preservation primer and other impurities. Learn more about the use of laser cleaning in welding work in separate article.
Processing of the welded joint
Case: Nuclear power industry
Objectives: During construction of nuclear power plants, stainless steel connection crosses are welded on a daily basis. Cleaning of the welded joints is required. The mechanical cleaning takes a long time, causing construction work to stall. The delay in commissioning of the plant is costing the company billions of rubles. The company was looking for new methods that would speed up the cleaning process.
The Pokkels solution: The F-Clean laser system helped the company significantly reduce the time it takes to prepare metal surfaces for welding and to clean welded joints quickly, helping to speed up the power plant construction process.

Local cleaning for surface diagnostics
Laser equipment is used by companies for research and diagnostics: checking the condition of a welded joint, nondestructive testing, etc. A wide range of settings of laser radiation parameters allows to interact with the surface in different ways. For example, to intentionally create the required morphology on the metal surface.
Case: Metal production
Objectives: The company is conducting an experimental study to create nickel alloys for electroplating lines. The metal is coated and circular holes are made in several areas. A different structure is then created at the holes and nickel is deposited on the cleaned metal. This produces nickel rondels that are used to deposit nickel in electroplating baths. The main task is to structure the surface so that the nickel begins to deposit and the rondel grows properly. Other than laser equipment, there are no alternative solutions to this task.
Pokkels solution: The F-Clean laser system helps to dissolve the metal by removing the coating with a stencil laser and to perform the patterning of the holes. The customer continues to experiment with different surfaces.

Reducing the coating layer
Overcoating a product causes the product to be defective. The F-Clean laser system can reduce the layer without damaging the surface due to the nature of the laser light: the coating is removed in layers, so you can adjust the height of the coating to be removed.
Case: Tube manufacturing plant
Objectives: Each pipe is treated with a protective layer of intermetallide. The finished pipes are connected with a coupling. If too much intermetallide has been applied, the pipe will not thread. It is not possible to remove the coating mechanically without damaging the threads. Such a product is scrapped.
The Pokkels solution: The F-Clean laser system makes it possible to normalize the thickness of the coating without damaging the threads, by applying it evenly over the entire surface. The manufacturer saves resources because there is no need to replace the pipe with a new one.
