Fiber laser technology in providing marking traceability

Laser marking has grown significantly important because of the chain visibility value. Fiber laser technology allows parts to be marked before heat treatments and to be reliable after the process. Nowadays, we can consider that fiber laser technology made a revolution in traceability capabilities.

Traceability is the ability of parts and products tracking across the supply chain. While different marking models can offer just individual part traceability before the hard processes, fiber laser marking keeps high legibility both before and after, for example, heat treatments. 

Despite the fact that fiber laser technology can achieve high-quality and high-contrast identifiers, the fiber laser marks are constant and provide a high level of legibility after heat treatments that transform the product’s surface. When a product has been treated with heat, it undergoes thermal expansion and then returns to the usual size. That is why many forms of identification lose their legibility.

Fiber laser systems allow reliable traceability by giving highly customized identifiers with regulated sizes. In comparison with the other marking systems, fiber laser technology provides many dimensions that can fit all the particular needs.

A fiber laser was named thanks to its laser that is produced by an optical fiber and has been treated with rare elements. These elements provide low-energy inputs for producing high-energy outputs. For high legibility achieving, the fiber lasers should meet several requirements. First of all, fiber laser power needs to be between 50W and 100W to provide the marking degree. Secondly, environmental factors like moisture and dust can influence the fiber laser‘s effectiveness. IP ratings are applied to ensure that fiber lasers work in the optimal environment. For the best results, there is a necessity for a high IP rating. 

In marking, a fiber laser creates etchings on the product surface and provides more space between the sections of the marking. As a consequence, these marks, produced by fiber lasers, are less likely to lose readability after heat treating. So in the future, they can retain a wide amount of information. 

Fiber laser technology is the only way that allows achieving individual identification without slowing down the supply chain.
