What could be the possible reasons for decreasing the corrosion resistance when increasing the laser power?

I studied the effect of laser power on corrosion properties of micro-alloyed HSLA (API X70) steel. The laser powers used for laser surface melting (LSM) are 2, 2.5, 2.75, 3, 3.5, and 4 kW. When...
