Abstract
The metal oxides of marine steel affect, the quality of welding seriously. The laser is used to remove metal oxides, and improve the surface properties such as interfacial bonding strength. However, the important part of laser removal of metal oxides is mechanism research. In this paper, in order to reveal the physical mechanism of laser removal of metal oxides, laser-induced plasma spectroscopy was used to collect the spectral information of laser removal of oxides from marine steel(Q235B). Temperature rise model of laser heating was used to analyze the spectral intensity of metal substrate and oxide. The intensity and electron density of the spectrum were studied, and the mechanism of laser removal was discussed.
