Anneal Marking-Sophia

Anneal Marking

Anneal marks is to heat the work piece with a laser beam to form an oxide on stainless steel surface.

And it creates a color change to the surface of the work piece.

Generally, the color of the mark is black.

But it can achieve other colors including red, green and yellow depending on  temperature on the material.

In the anneal marking process the material surface is not melted so no material is removed and the mark is achieved through the solid state growth of an oxidised layer.

The challenge is to produce a permanent mark which can be easily read.

Then our G4 70W HS-H fiber laser was tested on stainless steel and is able to achieve a high quality, dark mark which can be read from most viewing angles with a process time of 11 seconds to produce 26 characters, 10mm in height.

The HS-H type laser is mainly used for applications which require fast processing of large areas.

This is because the higher M² value of the HS-H type laser produces a broader energy distribution and therefore does not have a hot-spot like most single mode lasers.

And this type of mark can be made on some other types of steels and cast iron but the result is very dependent on the grade.
