Renovation of equipment, spare parts, laser processing and cleaning
The main areas of application in the primary treatment stage include the removal of oxides, films, paint, adhesives, oil stains, etc. In addition to external material removal, we laser refine surfaces using a special process to improve the strength and consistency of joints in a variety of applications - from paint preparation to creating durable, reliable mechanical coatings and joints for gas turbine, heavy industrial and transportation equipment renovations. Laser surface finishing has many advantages over traditional processes such as sandblasting, dry ice blasting, wet bath deposition and hand sanding.
Surface cleaning is a procedure that is primarily performed in high-speed scanning using large spots and low pulse energy. When it comes to cleaning oil and surface contaminants, a large light spot with the least amount of pulse and line overlap is used to quickly clean a lightly soiled surface.
Surface cleaning can impart a variety of positive characteristics to the metal being processed. In primary laser processing, the surface takes on a ready-made appearance for subsequent further processing, such as welding. Laser cleaning has the dual benefit of cleaning the surface and providing mechanical interaction to improve subsequent joints.
Laser cleaning of the surface of turbine blades:
When cleaning the surface of a blade blade, a laser installation is quite efficient and also imparts additional properties to the cleaned alloy due to a specific modification of the surface layer. This significantly reduces the time required to perform routine maintenance and allows you to save money by reducing the downtime of expensive equipment.
Preparation of particularly important and critical parts for flaw detection:
Laser processing has a wide range of applications:
- cleaning of welded seams of pressure vessels,
- cleaning of welds and connections of loaded elements and structures,
- cleaning of pipes of various types (OK, tubing, SBT, coiled tubing), as well as submersible pump rods.
- cleaning surfaces before applying protective coatings,
- removing the oxidized layer from the welded ends.
- cleaning surfaces before applying coatings,
- removing the oxidized layer from the welded ends.
- cleaning of centrifugal pump stages.
- preparation of metal surfaces for the application of paints and anti-corrosion coatings,
- removing tarnish from stainless steel surfaces.
Cleaning the aluminum surface from oxide film
An oxide layer or oxide film appears on the surface of aluminum or alloys based on it during natural contact with the environment (during oxidation with oxygen). In turn, the oxide layer serves to protect products from further corrosive effects, but can have an adverse effect on the technological process during further welding or gluing. Laser cleaning removes this oxide layer from the surface, thereby improving adhesion or weldability.
Cleaning steel from carbon deposits
Cleaning parts of shut-off and control valves
The presence of solid particles in gas leads to abrasive wear of expensive shut-off valves. Scratches and scratches appear on the surface of ball valves, violating the protective properties of galvanic coatings. When repairing them, it is necessary to remove the damaged electrochemical coating from the surface of the ball before restoring it. This process is carried out in an electrolytic bath by electrochemical etching. In this case, etching of the ball material inevitably occurs, leading to a change in the geometric dimensions of the entire product, which is unacceptable. The use of laser cleaning technology in this case makes it possible to selectively remove the old coating from the surface of the ball while maintaining its geometric dimensions.
Surface cleaning is one of the basic technologies in many industries. For some types of production - welding, paint and varnish, galvanic - surface cleaning is a pressing issue, since high quality surface cleaning guarantees a long service life and reliable operation of various products. Cleaning in general is the operation of removing surface layers formed by any contaminants or coatings, sometimes even including the main layer of material.
It should be noted that surface cleaning consists not only of removing organic and inorganic contaminants from the surface and previously applied coatings that have lost their service properties during operation, but also in a broader sense, in addressing issues of technological and operational heredity of the surface layer, which may be accompanied associated effects, namely:
- Improving the tribological properties of the surface (R-Profil, W-Profil, P-Profil surface, stabilization of the coefficient of friction, etc.).
- Activation of the surface of the material.
- Redistribution of residual surface stresses.
- Improving the mechanical, corrosion, physico-chemical properties of the surface.
- 1SpeedThanks to the high focusing of the beam, you will get the desired result in just a few laser passes. Ease of use and integration into technological processes
- 2EffectivenessWith a minimum of effort and time spent, you will get an ideal product without traces of corrosion, suitable for further use
- 3AccuracyYou can selectively work only with a certain area by setting the desired pulse power. At the same time, even on grooves and grooved surfaces, laser cleaning of metal will be effective and efficient. Selective and layered removal of the processed layers is possible
- 4QualityThe laser completely removes all traces of dirt, leaving behind a smooth metal surface without damage
- 5SafetyThe processed material is not destroyed during exposure, there is no risk of damage to the metal from which you remove oxidation, film, rust or paint if you choose a pulse cleaner. Compared with mechanical and chemical methods of exposure, this method is not traumatic — there is no human contact with the treated surface, and it is environmentally friendly — there is no release of toxic fumes
