Laser cleaning of stainless steel
Fast cleaning, no consumables, no waste and no dust are the reasons why laser technology is increasingly being adopted in factories that process stainless steel. Learn more about the uses and capabilities of laser systems from our article.
Laser cleaning technology may be of interest to companies that use stainless steel in the production process. Laser beam helps to prepare the surface for welding, to treat the surface after operation to give it its original appearance. Pokkels equipment successfully copes with these tasks in various industries.
Nuclear power industry
One of the key components of a nuclear power plant is the stainless steel water piping system. In the production of such systems, stainless steel surfaces must be cleaned and welded joints must be prepared. Conventional cleaning methods take longer than laser cleaning and also add a number of complexities related to waste disposal.
Rosatom uses F-Clean laser equipment in the construction and maintenance of power plants. Pokkels devices restore the appearance of stainless steel surfaces after use and eliminate tarnishing. The company was able to save money that they used to spend on chemical treatment, storage and disposal of waste.
Laser cleaning of the weld
TMC specializes in the production and repair of equipment for the food industry, in which stainless steel is a key material. The company carries out continuous treatment of various steel structures and surfaces. The use of chemicals is prohibited, and mechanical treatment leads to deformation of the accessory.
Laser equipment is used in repairs to clean the cases and interior surfaces of stainless steel equipment. Stamps and baking dishes are effectively cleaned. Reduces the surface roughness of the die cutter, which helps reduce friction and pressure on the food product during die cutting.

City transportation services
Public transport stops are made of stainless steel sheet, which over time oxidizes, corrodes on the fasteners, and there are traces of graffiti. Chemical cleaning means the added complexity of cleaning up chemical waste. The mechanical method does not allow to evenly clean the surface of the stop because of the complex shape.
Laser technology removes dirt without damaging the metal and cleans all shapes of surfaces: blunt corners, hard-to-reach places. After surface treatment with F-Clean laser equipment, there is no need to additionally mechanically grind and polish the surface.

Manufacturers of stainless steel products
Making equipment from stainless steel sheet requires cleaning of welded joints and restoration of the material surface after storage. The chemical method proved to be insufficiently effective.
Laser equipment is used for preparation for welding and cleaning of welded joints from oxides and traces of tarnishing. The weld is cleaned without impurities or damage.
Laser cleaning of stainless steel sheets
Pokkels equipment is also used in other areas. Large pipe rolling companies use our units for descaling large-diameter pipes. Automotive repair and restoration companies use F-Clean laser systems when working on body parts and exhaust systems.

How the laser works
Thanks to the wide range of settings, the laser equipment can achieve various results: from cleaning dirt to creating surfaces with a specific morphology.
When cleaning, the laser beam affects the contamination layer without damaging the metal. A high density of laser radiation is created on the surface and the contamination evaporates. Laser cleaning leaves no residue: the polished surface, textures and patterns will remain as they are.

Automation of laser cleaning
Pokkels develops customized automated laser systems.
Our specialists design complex automated systems. The robotic complex can weld the product and prepare the weld, and then clean the finished weld from oxides and tarnish marks. The result is identical, marketable products with no need for post-treatment. The system can be integrated into an existing production line.
The automation process allows to configure the cleaning parameters, the laser mode, the parameters of laser radiation sweep: change the beam width, switching on and off at specified moments.
It is possible to use existing conveyor lines, as well as the development of any coordinate systems to automate cleaning.
Pokkels develops systems in a variety of form factors. For example, in the arm shape for machining metal surfaces along different trajectories.The robotic system can also create texture, roughness on the surface of stainless steel.
The main advantages of an automated laser system:
- twofold productivity increase continuous operation
- without stopping production increased treatment
Advantages of laser equipment
- Selective surface treatment. For example, the weld is cleaned of tarnish without affecting the base metal, eliminating the formation of craters or cracks.
- Laser cleaning is one of the most user-friendly, environmentally friendly and highly resource-efficient ways to treat surfaces. Service life of our devices is at least 10 years.
- Competitive advantage: reduced production time and improved product quality.
- Pokkels devices do not require additional costs other than electricity: at the rate of 1 kW per 1 m2.
- The equipment can be leased.
