Fiber lasers have entered the jewelry workshop. With different powers and modes they cut, engrave, mark and clean metal.

![Steps of the technique: Choose the process, Prepare the piece, Set, Test, Run, Check](https://www.711grados.com/media/diagrams/laser-steps.en.svg "Summary of the steps")

## Cutting

It cuts thin sheet with a precision of tenths of a millimeter, with no cutting tool.

## Engraving and marking

It engraves letters, drawings and hallmarks into the metal; it also marks the inside of rings without deforming them.

## Cleaning

It removes oxides and residue from the surface without abrasives.

## Welding

With another mode, the laser is used for [laser welding](https://www.711grados.com/en/laser-and-spot-welding/).

## Safety

It requires specific eye protection and suitable enclosures or filters.

## Step by step

1. **Choose the process.** Cutting, engraving, cleaning or welding.
2. **Prepare the piece.** Clean and hold.
3. **Set.** Power, speed and focus.
4. **Test.** Run a test on scrap material.
5. **Run.** With eye protection and extraction.
6. **Check.** Compare with the design.

## Tools and materials

- Fiber or CO₂ laser
- Glasses specific to the wavelength
- Fume extractor
- Design software

## Common mistakes

- Using glasses not suited to the laser.
- Reflective metals without power adjustment.
- Forgetting fume extraction.
- Focusing badly.
