PURPOSE: A joining method for heterogeneous materials using a temperature measurement control laser is provided to obtain a composite material with high heat resistance, corrosion resistance, and shock resistance by welding a metal plate and a ceramic coating film with metal filled in holes formed in the ceramic coating film. CONSTITUTION: A joining method for heterogeneous materials using a temperature measurement control laser comprises the steps of: coating ceramic of a predetermined thickness on a metal plate(S100), irradiating the ceramic coating film with laser beams to form holes at regular intervals(S200), measuring the temperature of the metal plate through a temperature measurement control unit and monitoring changes in the measured temperature(S300), determining whether the gradient of temperature variation abruptly changes(S400), and terminating the projection of the laser beams after a predetermined time in case of abrupt change and welding with molten metal filled in the holes(S500).
