Laser Marking Process Parameters

Pulse 5 ns to process the surface under normal atmospheric.

Laser marking process parameters.

Depends on different materials and the marking effects you want so for a new operator may need conduct dozens of trials to know the ideal marking parameters for each material and even some experienced engineers. For objective assessment of color changes a cie color difference formula delta e ab was. Plastics which as a result of a laser marking process show no contrast in the pre doping phase display a legible inscription after the additive has been added. Altering this frequency creates different marking effects.

This is an application that is often used to print the time of manufacturing and the expiration date on the product. This paper presents the results of the measurement and analyses of how the laser marking process parameters influence the colors created on titanium. This parameter is used to adjust the laser output frequency by directly operating the q switch. In marking metal and plastic there is a setting parameter range for reference to test speed 100 2000 adjustable power 30 80 adjustable frequency 5 30.

An additive is mixed into gabocom s pe pipes in order to ensure that the laser marking process generates high contrasts. This results in high productivity and cost benefits during manufacture. In this work laser surface marking was performed on titanium substrate using doubled frequency pulsed nd. Yag green laser 532 nm.

The q switch is an electro optical system which controls the opacity of a lens making it possible to change the laser beam frequency. The color of marking is different than a mark produced by an inkjet printer. Depending on the laser parameter settings certain materials can also be marked without damaging the surface. The investigations were performed using a commercially available industrial pulsed fiber laser.

The aim of the current study attempts to investigate the effects of laser etching parameters specially the scanning speed ns peak power kw frequency khz and heat input j mm 2 on the corrosion resistance and variations in surface roughness properties of the marine. What materials can be marked with a laser. Laser etching process is used for marking those materials which cannot be marked by conventional machining processes.
