| Abstract Scope |
This study examined the thickness and microstructure of the heat-affected zone (HAZ) resulting from laser cutting various metal alloys under different processing conditions. Steel, aluminum, and brass samples were cut using a GWIKE M3 Ultra system equipped with a 1500W fiber laser. Laser power and traverse speed were systematically varied to evaluate their influence on HAZ development. After cutting, samples were polished and etched to reveal the underlying microstructure, which was analyzed using optical and electron microscopy. Results show that laser power has a pronounced effect on HAZ thickness and morphology, independent of material, and optimal processing parameters were identified for each alloy. |
