Laser cleaning is a non-contact and safe process that has many advantages, since there is no need for chemicals, sand or any other waste material, thus the constant costs are reduced to a minimum.

Laser cleaning in contrast to traditional cleaning processes

Energy-saving and environmentally friendly cleaning process. Traditional cleaning methods, such as sandblasting or solvent solutions, require significant energy consumption and have a negative impact on the environment. The advantage of the laser over traditional cleaning is that there is no need to use solutions or other materials.

It is an ecologically neutral, economical and practical choice. Laser cleaning has countless advantages over traditional surface cleaning methods that help work processes. The stricter environmental protection rules and the increasing quality requirements can represent significant burdens for the various manufacturing industries, which can influence the price, demand and supply of products in the long term and this affects competitiveness.

Laser cleaning is not only an environmentally friendly process, but also involves only a one-time investment cost. With continuous maintenance, the service life of the equipment increases. It will pay for itself in a short time, as there is no need for chemicals and yield materials, so the corresponding storage and transport costs of these do not have to be taken into account. In addition to all this, the energy consumption is also much more favorable compared to traditional machining machines.

Sandblasting and laser cleaning are used to clean, prepare and renovate surfaces. Both technologies have their advantages and disadvantages.

Sandblasting:

One of the advantages of sandblasting is that it can quickly and efficiently remove rust, paint and other contaminants from large surfaces. In addition to its cleaning effect, it can also be a good choice for surface preparation, as it leaves a rough surface.

As with all technologies, this process has its drawbacks, a large amount of dust and waste is generated, which poses risks to the environment and human health. It can not only improve the surface, but also damage it, as sandblasting can also wear down the surface. In addition to the full protective equipment, it is also against loud and tiring work.

Laser cleaning:

Laser cleaning has many advantages, including micron accuracy, precision and a contact-free work process. It removes dirt with great precision without damaging the raw material. During the cleaning process, little waste is generated, as it turns most dirt into dust or gases, which we can remove from our environment by exhausting it, so it does not have a harmful effect on health either. There is also no need for post-processing before further processing, as it leaves behind a perfect surface.

Laser cleaning also has its disadvantages, it is not the best solution for large surfaces, as it was developed for precise work. The investment cost is relatively high, but with regular maintenance we can increase the duration of our laser equipment.

It is mostly used for rust removal and paint removal, on workpieces where the surface is coated after cleaning. (e.g. car rims, vehicle chassis, building steel structures, etc.) Ideal choice for both pre- and post-treatment of welding seams.

It can be used to clean and remove certain surfaces. fiberersx laser cleaners are precision tools. They easily clean workpieces and tools from the hardest rusts, oxides, deposits, oils and paints, etc. So it is a perfect solution for cleaning tools and parts, because there is no loss of material during the cleaning process, which is an important requirement in industries. During laser cleaning, the surface remains undamaged, in contrast, this is not guaranteed with a traditional cleaning process. At the same time, the process is extremely fast, thus improving productivity, which also guarantees greater profits in the long run.

In summary, the technology is suitable for the removal of rust, oil, grease, graphite, various oxidations, paints and coatings, as well as for the decontamination of raw metal materials.

It provides precise and versatile use, with which we can cut materials of specific shapes and sizes. We can also choose from a wide range of materials, such as metals (steel, aluminum, titanium), plastics (acrylic, polycarbonate, polypropylene, pcb), wood (plywood, MDF), composites, fabrics and textiles. The task is completely user-friendly, contact-free, and the possibility of human error can be ruled out, since the precise cutting is controlled by a computer-controlled system. It can be used especially for projects where we need a very precise cut, which affects further use. Areas of application include industrial production (automotive industry, aerospace industry, electronics), individual production and prototyping, medical industry and the electronics industry (circuit boards, housings).

Laser cutting has many advantages, including precision and accuracy, laser cutting can achieve tight tolerances of up to 0.001 inches, making it suitable for creating detailed and complex designs.

Clean and Smooth Milling:

There are no burrs during milling, so there will be no waste. During the process, only dust is generated, which is removed from the milling area by suction, so it is an environmentally friendly solution. The result is an excellent surface quality, which requires minimal post-work or can even be dispensed with.

Among its disadvantages, we can mention that a 4-5 axis milling machine is preferable to a precision laser milling machine for processing large parts.

Industrial applications:

Laser milling in industry is a highly efficient and versatile technology that offers many benefits to industries including automotive, aerospace, electronics, and medical. Due to its precision, speed and flexibility, laser milling continues to play an increasingly important role in industrial production.

Traditional technology and laser milling:

The comparison of laser milling and traditional milling technologies can be examined from several points of view.

1. Work piece material and applicability:

Laser milling:

It easily performs the precise machining of small parts, and the list of machinable materials is quite broad, from very hard materials (ceramics, carbide) to weaker materials (metals, plastics, glass, wood).

Traditional milling:

It offers a simple solution for machining general materials (e.g. metals, wood, hard plastics), especially for large parts.

2. Accuracy and surface quality:

Laser milling:

Its surface quality and accuracy are excellent, it is also capable of creating microscopic details with the help of the appropriate program.

Traditional milling:

Precision depends on the setting of the tool, and wear during the process can worsen the final results. A simple milling machine cannot go down to microscopic details, but a precise and beautiful surface quality can be achieved with it.

3. Speed ​​and productivity

Laser milling:

There is no need to change tools, so we can achieve quick transitions, as the maximum number of parameters must be rewritten in the program. The working speed is high, especially for thin materials.

Traditional milling:

Since the work is done with tools, it may be necessary to change tools for different operations, which reduces productivity.

4. Tool wear and maintenance

Laser milling:

There is no physical contact with the workpieces, so there is no tool wear, so maintenance costs can also be reduced.

Traditional milling:

When working with tools, wear and tear is common, which requires regular replacement. Moving parts on machines can increase maintenance costs.

5. Environmentally friendly and safety

Laser milling:

The work process involves less vibration and noise, while observing the precautions, the work is safe and can be controlled remotely. In addition to all this, a small amount of waste is generated, with which we can also meet environmental protection requirements.

Traditional milling:

Due to the chipping, more dead blue is produced than with laser technology. The emission of noise and vibration is also louder, and there is also the possibility of tool breakage due to mechanical movements.

6. Costs

Laser milling:

It involves a higher initial investment cost, but in return the operating and maintenance costs are more favorable.

Traditional milling:

It may have lower initial investment costs than laser technology, but higher operating costs due to frequent tool wear and maintenance.

Both procedures have their own advantages and disadvantages, the completion of the task affects the acquisition of the appropriate device. Laser milling excels in terms of speed, versatility and precision, while conventional milling processes are widely applicable for larger and simpler workpieces. The choice of the right technology depends on the particular application need.

Laser welding does not require wire material or shielding gas. The process can be carried out with a manual tool or with fully automatic equipment.

Precision laser welding equipment are special tools designed to perform fine and precise welding tasks. Precision laser welders are able to work with very tight tolerances, enabling the welding of small and sensitive parts. These devices introduce minimal heat into the material, which reduces the risk of deformation and damage to the material. Precision laser welding systems can often be integrated into automated production lines, increasing productivity and reducing the chance of human error. They have advanced control systems that allow precise monitoring and adjustment of the process. Precision laser welding equipment has revolutionized welding processes in many industries, providing high levels of accuracy, reliability and productivity.

The differences between precision automated laser welding and traditional laser welding are significant in several ways. Both technologies are used to connect materials, but they differ in their application, use, and process control.

Comparison of laser welding and conventional welding:

Precision automated laser welding:

Automation:

In this case, the welding process is carried out by automated systems that use computer-controlled tools and robots.

Accuracy and repeatability:

Automated systems provide extremely high accuracy and repeatability because programmed movements are performed without human error.

Speed:

Automation enables welding at higher speeds, which increases productivity and reduces lead time.

Application:

Used in high volume production such as automotive, electronic device manufacturing and other industrial applications where precision and efficiency are key.

Costs:

Higher initial investment costs are typical for acquiring and installing automated systems, but they pay for themselves in a short time due to long-term cost-effectiveness and productivity.

Conventional laser welding:

Manual control:

Conventional laser welding is often manual, where the operator controls the laser and materials, and this process is prone to human error.

Accuracy:

Accuracy is highly dependent on the skill and experience of the operator. Due to manual control, it is more difficult to maintain constant quality and precision.

Speed:

Manual control limits the speed of welding as the operator’s physical capabilities set a limit.

Application:

Generally used in small-volume production and repair work, where flexibility and operator experience play an important role.

Costs:

With lower initial investment costs, processes can be slower, increasing labor costs and reducing productivity.

Precision laser welding in industry:

Precision laser welding plays an increasingly important role in various sectors of industry, thanks to the high precision, speed and reliability provided by the technology. Precision laser welding can benefit several industrial areas, including.

Automotive industry

In the automotive industry, laser welding is used to join different parts of the car body and chassis. Automated laser welding offers a fast and precise solution, reducing production time and increasing productivity. Welding aluminum and other lightweight materials used to improve fuel efficiency is particularly beneficial due to the precision of laser welding.

Electronics industry

Medical technology

In the production of medical devices such as pacemakers, catheters and other implants, laser welding ensures strict tolerances and sterile manufacturing conditions. In the production of small surgical instruments, where precision is essential, laser welding is extremely useful because micron.

Air and space industry

The welding of structural elements of aircraft and space vehicles, which require high strength and low weight, is an ideal application area for laser welding. In the production of turbine and other gear components, laser welding ensures high accuracy and reliability.

Precision instrument production

Laser welding ensures the necessary precision when connecting and repairing the small parts of watch mechanisms. In the manufacture and repair of microscopes, binoculars and other optical instruments, laser welding enables precision joining.

Manual laser welding does not require wire material or shielding gas. The process can be carried out with a manual tool or with fully automatic equipment.

A manual laser welder is a device that uses a laser beam to join metals or other materials. The advantages of laser welding include high precision, minimal thermal effects, flexible and versatile use and high-quality welds.

Main features:

Precise controllability of the laser beam enables delicate welding work, which is important for parts with complex geometries. During work, the heat-affected zone is small, so the surrounding materials are deformed less or not at all, and require less or no post-treatment. The listed characteristics enable industrial use, for example in the automotive industry, metal industry, etc. It offers an excellent opportunity for welding body panels, exhaust systems, metal pipes, metal parts and other metal parts.

Conventional welding processes:

Conventional welding processes, such as MIG (Metal Inert Gas) and TIG (Tungsten Inert Gas) welding, use different methods to join materials and share many similarities with laser welding. Below, I will present the traditional welding processes in more detail and compare them with laser welding.

Arc welding:

During arc welding, the heat generated by the electric arc melts the base material and welding material (if used), thus creating the joint. There are several types of arc welding, some of which are:

1.MIG/MAG (GMAW – Gas Metal Arc Welding):

In this process, a continuously fed welding wire serves as electrode and filler material. During the process, a shielding gas (inert or active) flows around the arc and weld pool to protect the molten metal from atmospheric contaminants.

Advantages: High welding speed, easy to automate.

Disadvantages: Less suitable for very thin materials, sensitive to wind due to the use of shielding gas.

2. TIG (GTAW – Gas Tungsten Arc Welding):

In this process, the tungsten electrode does not melt, but only supplies the arc. The filler must be added separately, and an inert shielding gas (usually argon) protects the molten metal.

Advantages: High quality and precision welding, good for thin materials.

Disadvantages: Slow welding speed, requires higher dexterity.

Comparison with Laser Welding:

Similarities include the formation of a melt (the base material and the welding material melt and then create a bond during cooling), although the use of welding material is not always necessary in laser welding. Another similarity may be the use of shielding gas, although this is not always necessary in the case of lasers, only in the case of certain materials.

Differences:

Heat source:

In traditional welding processes, the electric arc supplies the heat, while in laser welding, the focused laser beam supplies the heat.

Accuracy and Heat Effect:

Laser welding is extremely precise and has less heat effect, so it causes less or no distortion in the material, while traditional welding processes have a larger heat effect zone, so there is more chance of distortion.

Speed ​​and Automation:

Laser welding is faster and easier to automate, while traditional welding processes have different speeds and automation options.

Costs:

The initial investment is higher for laser welding, but consumables and post-work costs can be lower.

Application Examples:

MIG/MAG Welding:

Suitable for welding large metal structures, such as car bodies and construction structures.

TIG Welding:

Fine and precision work such as welding stainless steel and aluminum and joining pipes and wires.

Laser welding:

Precise and beautiful seams can be created during welding, neither wire material nor shielding gas is necessary for welding, only in the case of certain raw materials.

Laser marking ensures long-term traceability because it does not wear off like paint or ink or tear like a label. Marking is considered a basic technical function. It can be varied as needed with any of our technologies.

Laser marking is a modern and efficient technology that uses laser beams to create permanent markings on various surfaces. It can create different markings on a wide range of raw materials. This technology is used in many industries, including automotive, electronics, medical device manufacturing, and jewelry. Depending on the task, we can create a mark in several ways, e.g.; surface marking, deep marking, laser engraving. High accuracy and detail are one of the main characteristics of precision laser marking, durability can also be classified here, because they are resistant to wear, chemicals and temperature changes. Another big advantage of traditional marking technologies is that it can be used on almost any material, including plastics, metals, ceramics, metals, etc. In addition to its flexible and precise use, the automated laser marker results in fast and efficient work, with which we can also improve production time. It is already used in many industries, including the automotive industry, electronics industry, medical industry, plastic industry, metal industry, railway industry, packaging industry, etc. Identifying components and devices with serial numbers, QR codes or DATA Matrix can be useful in several industries, but the identification of manufactured products is perhaps the most important, so that the exact production can be traced at any time, in the event of a possible future error.

Traditional marking techniques:

Mechanical engraving:

A simple, reliable method, but it is less accurate and can cause damage to the material, its detail is limited and it is a time-consuming process.

Ink printing:

Screen printing:

Screen printing is an extremely versatile and efficient printing technology that has many advantages, especially in terms of the thickness of the printed ink layer and its compatibility with various materials. Its main features include multi-color printing, a thick paint layer, it can be used on several materials and is also suitable for marking slightly curved surfaces.

Offset printing:

The ink is applied to a printing plate and from there to a rubber cylinder, which is then applied to the printing surface. It is a fast and simple process, especially in the case of large quantities, but it can be applied to less material than the other technologies.

Stamping:

Stamping is a mechanical process in which pressure is applied to a material to create a permanent mark or deformation on its surface. This process is used in many industries and is suitable for machining a variety of materials. The downside is that the tools wear out during the process.

Chemical Etching:

Chemical etching is a material removal technique that uses chemicals to partially or completely remove the surface of a workpiece. This process is often used to machine metals, glass and semiconductor materials. We have several types of etching at our disposal, such as; micro-etching, which can be useful mainly for the electronics industry, photo-etching and general etching, where different acids and alkalis are used during the process.

Laser marking therefore has many advantages over traditional marking methods, especially in terms of precision, tool-free, durability and versatility. However, depending on the application area and specific needs, traditional methods may also be beneficial, especially for small quantities or low costs.

The creation of individual markings is not an obstacle with laser technology, we only need the right raw material and we can also create colorful markings with unique shapes.

Color laser marking

Color laser marking is not a widespread technology, but rather interesting from a design point of view. It is suitable for creating patterns and inscriptions in different colors. The colors can be created using several methods, all that is needed is the right raw material and setting. During the laser treatment of certain metals (e.g. stainless steel), an oxide layer is formed, which results in different shades of color. Different colors can be achieved by changing the thickness of the oxide layer and the parameters of the laser. The temperature changes caused by the laser can create various color shades, this procedure can be used especially for metals. Different color coatings can be created on aluminum surfaces with an anodic oxidation process. After applying special coatings or paints with surface treatment methods, the laser removes a certain layer of the coating so that colors become visible. For many materials, special coatings are used, which, after treatment with a laser, show different colors in the evening of the specially coated material. Of course, not only the raw material is decisive during the procedure, but also the programming. Thanks to the software, any graphic, pattern, text can be created and we can create several colors.

Laser marking can be used on various materials:

Metals:Stainless steel, aluminum, titanium and other metals that respond well to laser heat treatment and oxidation.

Plastics:Plastics with special additives that allow color markings.

Glass and ceramics:These materials can also be laser machined, although color markings may be more limited here than for metals.

Colored marking offers many advantages, it is just as durable as simple marking, resistant to wear, chemicals and drastic changes in temperature. High-resolution, detailed markings can be easily created based on vector files, and a print image can almost be converted. The process is fast and fully automated, as with other laser technologies.

Color marking for metals:

In the case of metal, the heat and energy of the laser creates various chemical and physical reactions on the surface. Colors can be achieved using different methods, the first being oxidation, heat treatment and material coatings.

Oxidation:

In the case of stainless steel, when it is treated with a laser, an oxide layer is formed, with which we achieve different shades of color. The colors can be changed by changing the thickness of the oxide layer and the parameters of the laser (e.g. intensity, speed, frequency).

Heat treatment:

The temperature changes produced by the laser can create various color shades on the surface. Changes in the crystal structure and surface of the metal caused by heat cause the appearance of colors.

Material coatings:

Special coatings are applied to some metals, which, after being treated with a laser, show different colors. These coatings can be oxide layers, paints or other special materials.

Applicable metals:

Stainless Steel:One of the most commonly used metals for color laser marking, as it can produce different colors through oxidation.

Titanium:It also responds well to laser heat treatment and can be obtained in different shades.

Aluminium:Colored markings can be made on it with special coatings and oxidation processes.

Copper and brass:These metals can also be suitable for color marking, especially with the use of special coatings.

All in all, color laser marking is a technology that provides a unique solution that is durable and precise. It is mainly used in some industries, where metal surfaces are visible elements, such as railings, interior of elevators, wall surfaces are interior design elements.
