Study on the laser cutting quality of ultra high strength steel

Ultra High Strength Steel (UHSS) has been used in vehicle as it able to improved durability of the vehicle while reducing the mass. Laser cutting process has been an alternative choice in trimming of the UHSS to regain the final shape. This study is intended to study the effect of input parameters o...

Laser cutting process has been an alternative choice in trimming of the UHSS to regain the final shape. This study is intended to study the effect of input parameters of Carbon Dioxide (CO2) laser cutting on the UHSS, focusing on the cutting quality and mechanical properties. CO2 laser cutting machine was used to perform the cutting process. Kerf width, taper angle and Heat Affected Zone (HAZ) region were evaluated as the cutting quality with variation on laser power, cutting speed and assisted gas pressure.
