In order to solve the problem that laser transmission was difficult to connect polystyrene and titanium, polystyrene treated with oxygen plasma was used for laser transmission connection with thin titanium treated by laser surface treatment. Mathematical model of laser transmission connection process parameters was established, and interactive influence of process parameters on connection strength was analyzed. The optimized process parameters were obtained. The results show that the bonding strength of polystyrene and thin titanium after treatment increases from 0.5MPa to more than 6.0MPa. Laser transmission connection problem of polystyrene and titanium can effectively be solved. The combination of the optimum process parameters can be obtained by optimizing the process parameters. The research makes the foundation for industrial application of the process.
