The utility model discloses a metal material surface dynamic temperature point measurement system based on reflectivity changes, include and add the thermal light source, adding the thermal light source and being connected with the metal sample, plated the metal layer material on the metal sample, the setting of metal sample is on the route that adds the heating laser beam that the thermal light source jetted out, and the metal sample is connected with reflective light intensity and changes the test system, and reflective light intensity changes the test system and is connected with the photoelectric conversion trigger. This system can acquire the dynamic temperature data surperficial like metal material commonly used such as aluminum alloy, copper who has the high heat conductance characteristic, causes unable welding heat galvanic couple, realizes the analysis and the aassessment of metal material laser irradiation fuel factor, provides the basis for optimizing laser parameter among the laser processing pro
