The Effect of CO2 Laser Scan Speed on the Properties of Groove Created on Stainless Steel Plate

Abstract

In this study, grooves were created on dual-phase steel with a 30 W CO2 beam at different scanning speeds. The geometric and structural properties of the grooves obtained were investigated. Measurements were made from detailed optical microscope images of the grooves created by laser on the material. In the measurements, the molten region of the groove and the width of the Purple-Brown heat tint, which is one of the heat bands seen in the steel materials during the heat increase, were examined. As can be seen from the graphs of variation of the molten region and the Purple-Brown heat tint against the scanning speed, both the width of the heat band and the width of the melted region decreased linearly as the scanning speed increased. The width of the molten zone remained constant when the scanning speed was 15 mm/s, and the width of the heat tint remained constant when the scanning speed was 25 mm/s.
