In this study, grooves were created on a 3 mm thick steel plate by using a carbon dioxide laser at different laser powers at a constant speed. High-resolution images of the laser-processed surfaces were taken with a high-resolution stereo microscope. The molten zone and heat-affected zone widths of the troughs were measured using the images. To reduce the error rate, measurements were made from 5 different regions on the obtained grooves. Finally, the changes in the molten zone and heat-affected zone widths against the applied laser power were examined graphically. As a result, it has been observed that the widths were increasing by laser power with slowing down. Heat Affected Zone and Molten zone widths have changed at the same rate. As the energy transferred to the material surface increases, both the Heat Affected Zone and the molten zone width has increased. The applied laser power has been studied from 40 W to 115 W. Heat Affected Zone Size increased almost linearly when laser power was increased from 40 W to 80 W. It has been observed that the HAZ size increase was less for higher power values.

Bu çalışmada, 3 mm kalınlığındaki bir çelik levha üzerinde farklı lazer güçlerinde ve sabit hızda karbondioksit lazer kullanılarak oluklar oluşturulmuştur. Yüzeyler lazer ile işlendikten sonra yüksek çözünürlüklü mikroskop ile yüzeylerin görüntüleri alınmıştır. Olukların erimiş bölge ve ısıdan etkilenen bölge genişlikleri, görüntüler kullanılarak ölçülmüştür. Hata oranını azaltmak için elde edilen oluklar üzerinde 5 farklı bölgeden ölçüm yapılmıştır. Son olarak erimiş bölge ve ısıdan etkilenen bölge genişliklerinin uygulanan lazer gücüne karşı değişimi grafiksel olarak incelenmiştir. Genel olarak lazer gücü ile genişliklerin yavaşlayarak arttığı gözlemlenmiştir. Isıdan Etkilenen Bölge ve Erimiş Bölge genişlikleri aynı oranda değişmiştir. Malzeme yüzeyine aktarılan enerji arttıkça hem Isıdan Etkilenen Bölge hem de eriyik bölge genişliği artmıştır. Uygulanan lazer gücü 40 W ila 115 W arasında incelenmiştir. Lazer gücü 40 W'tan 80 W'a çıkarıldığında Isıdan Etkilenen Bölge Boyutu neredeyse doğrusal olarak artmıştır. Daha yüksek güç değerleri için HAZ boyut artışının daha az olduğu gözlemlenmiştir.
