Fiber Laser Rust Removal – Important Tips & Tricks

Rust removal is an important part of any maintenance plan, as it can prevent further damage to metal surfaces. In recent years, fiber laser rust removal has become increasingly popular, as it offers a more efficient and costeffective way to remove rust from metal surfaces.

Fiber laser rust removal is a process that utilizes a highpower laser to quickly and effectively remove rust from a variety of materials, including steel and aluminum. With its ability to clean rust from even the smallest of surfaces, fiber laser rust removal is a great choice for any maintenance job. In this article, we‘ll discuss the benefits and processes of fiber laser rust removal, as well as provide guidelines for choosing the right laser for the job.

When should you worry?

You should worry about fiber laser rust if you notice any discoloration or corrosion on the surface of your laser machine. If the rust is extensive or if you don‘t know how to properly care for your laser machine, it is best to consult a professional to assess the situation and determine the best course of action.

Examples of signs of rust on a fiber laser machine include discoloration, flaking, pitting, or even corrosion. Additionally, if you notice any difficulty in starting the laser machine or any unusual noises, it may be a sign that rust is present. If the rust has been left unchecked for too long, it can cause permanent damage to your machine, so it is important to address the issue as soon as possible.

Discoloration in fiber lasers is caused by a number of factors, including the accumulation of carbon deposits on laser components, such as mirrors and lenses, as well as the presence of impurities in the air that can get into the laser cavity and create a hazy appearance. This discoloration can affect the performance of the laser by reducing the power output and beam quality.

Flaking and pitting are common issues that can occur when using a fiber laser cutting machine. Flaking occurs when the laser beam melts and removes part of the material, leaving a rough surface. Pitting occurs when the laser beam creates small depressions or indentations in the material. Both of these problems can lead to poor quality cuts and a decreased lifespan of the material.

How to remove rust using fiber laser?

The fiber laser rust removal process involves using a laser beam to vaporize the rust and other corrosion from the metal surface. The laser beam is focused on the surface to be cleaned and the heat from the laser beam causes the rust to vaporize, leaving behind a clean, rustfree surface. The process is very precise, allowing for rust removal from small and intricate areas.

One example of a successful fiber laser rust removal project is the renovation of a historic locomotive in Canada. The locomotive was covered in rust and corrosion due to years of neglect and exposure to the elements. The use of a fiber laser was chosen as the preferred method of rust removal due to its precision and ecofriendly nature. The laser was used to remove the rust and corrosion from the metal surfaces of the locomotive, resulting in a restored and rustfree locomotive that can now be used for its original purpose.

Fiber Laser Rust Removal

Here is the step-by-step guide to the rust removal process:

  • Gather the necessary supplies: protective eyewear, face mask, rubber gloves, and a fiber laser machine.
  • Put on the safety gear (eyewear, face mask, gloves) before beginning the process.
  • Place the rusty object to be cleaned on a flat, stable surface.
  • Set up the fiber laser machine according to the manufacturers instructions.
  • Adjust the laser power to the correct setting, usually between 10 and 20 watts.
  • Position the laser head directly over the rusty area and activate the laser.
  • Move the laser head slowly across the rusty area in a circular motion.
  • Monitor the progress of the laser cleaning process, and adjust the laser power if necessary.
  • Once the rust is removed, turn off the laser and allow the object to cool.
  • Use a damp cloth to remove any remaining residue.
  • Dispose of any debris created during the laser cleaning process according to local regulations.

Common Mistakes

One of the most common mistakes people make when cleaning rust from a fiber laser is not wearing protective gear such as eye protection, gloves, and a face mask. Without this protection, the user is at risk of eye irritation, skin irritation, and breathing in dangerous particles.

Another common mistake people make when cleaning rust from a fiber laser is not using the right cleaning materials. Many people mistakenly use abrasive materials, such as steel wool or sandpaper, which can damage the fiber laser and cause further rusting. To avoid this, only use nonabrasive cleaning materials such as a soft cloth, paper towel, or cotton swab.

A third common mistake people make when cleaning rust from a fiber laser is not cleaning the area thoroughly. Rust can spread quickly, so it‘s important to make sure the entire area is cleaned and all rust is removed. If any rust is left behind, it can continue to corrode and spread, leading to more extensive damage.

Lastly,  people make when cleaning rust from a fiber laser not properly dry the area. If the area is not thoroughly dried, moisture can accumulate and cause rust to spread. To avoid this, use a soft cloth to dry the area thoroughly and make sure no moisture is left behind.

Differences between CO2 & fiber laser in rust removing process

CO2 laser rust removal is a noncontact process that uses a laser beam to vaporize rust and other contaminants. The laser beam is focused on the surface of the metal and the vaporized rust is then removed with a vacuum. CO2 laser rust removal is fast and efficient, but it is also more expensive than other methods.

Fiber laser rust removal is similar to CO2 laser rust removal, but instead of using a laser beam, it uses a high-powered fiber optic laser. The laser beam is focused on the surface of the metal and the rust is then vaporized. The vaporized rust is then removed with a vacuum. Fiber laser rust removal is more precise and can be used on complex shapes, but it is also more expensive than CO2 laser rust removal.

An example of CO2 laser rust removal would be a car part that has been exposed to the elements. The laser beam can be used to vaporize the rust, making the part look new again. Alternatively, fiber laser rust removal would be a complex metal sculpture that has rust spots. The laser beam can be used to precisely target the rust spots, vaporizing them and leaving the sculpture looking like new.

Consider these before buying a rust remover

Before purchasing a rust remover, there are several factors to consider. First, you should determine the severity of the rust. If it is light and surface rust, you may not need a strong chemical rust remover. A mild abrasive cleaner and some elbow grease may do the job. If the rust is more severe, you will need to choose a rust remover that is up to the task.

You should also consider the type of surface you intend to use the rust remover on. Some rust removers are acidic, and therefore can damage certain types of surfaces. If you plan to use it on a delicate surface, such as aluminum, stainless steel, or painted surfaces, you should choose a rust remover that is specifically designed for these surfaces.

The cost is also an important factor to consider. Rust removers can range in price from a few dollars to several hundred dollars, depending on the size and strength of the chemical. It is important to consider the cost of the product against the cost of replacing the item if the rust is not removed.

Finally, you should look at the safety instructions for the rust remover. Many rust removers contain strong chemicals, and should only be used with proper safety equipment, such as gloves and safety glasses. You should also follow the manufacturer‘s instructions for proper disposal and storage of the product.


The use of fiber lasers for rust removal is a great option for those looking for an effective and efficient way to remove rust from their metal objects. Not only is it efficient, but it is also very safe. Fiber lasers are powerful enough to be used to remove rust without damaging the metal underneath. Furthermore, with proper maintenance and care, fiber lasers can be protected from rusting, ensuring that the laser can be used to remove rust for many years to come. With its ease of use and reliable performance, fiber laser rust removal is a great choice for anyone looking to remove rust from their metal objects.
