Laser metal degreasing before soldering or welding

Degreasing is an important step that determines the quality of the future connection. Alkalis and solvents as well as mechanical brushes are often used for metal degreasing. Let’s look at the typical problems with conventional degreasing methods and compare them with laser equipment.


Cleaning speed

The chemical method of degreasing is time-consuming. The product must be soaked in the solution, sometimes the solution must be pre-heated. Then it is necessary to rinse the product and dry it properly. Only after that does soldering or welding may be performed.

Why laser?

Laser equipment allows you to start degreasing immediately without any pre-treatment. After treatment, you can start welding immediately

By-products of cleaning

Chemicals require disposal. You have to spend extra resources and time as a result: hire cleaning and housekeeping staff, and pay for chemical waste disposal services.

Why laser?

No by-products. All cleanable contaminants evaporate. Laser cleaning requires just one person — a laser operator.

Local treatment

During chemical treatment, the part is completely immersed in the solution. Moreover, sometimes it is not enough just to degrease the part: it is necessary to clean the product from persistent contaminants, such as rust.

Why laser?

The precise positioning of the laser beam enables selective treatment: clean only the area that needs to be cleaned. Flexible device settings allow to work with a variety of contaminants.

Process automation

Pokkels offers a wide range of partially and fully automated laser systems. We develop a complex that fulfills your production tasks of degreasing and cleaning surfaces. 

The robotic system combines the high effectiveness of a laser cleaning system with the precision of an automated system. It is designed for non-stop operation while maintaining low operating costs.

The main advantages of an automated system: 
  • advanced technology
  • increased treatment accuracy
  • similar performance
  • increased productivity
  • tailored to your needs
  • non-stop operation 24/7.

The robotic complex is capable not only of degreasing surfaces, but also of carrying out welding work. The device pre-cleans the surface, welds and cleans the product of tarnishing and oxide marks. As a result, you get an exactly reproducible result: the same appearance of the finished products.
