Abstract
A control apparatus for energy beam hardening which has an electromagnetic wave detector for detecting an electromagnetic wave irradiated from the surface of a hardened portion to which an energy beam is being emitted, a temperature converter for converting a detection signal from the electromagnetic wave detector to a temperature, hardening characteristics presuming means for presuming hardening characteristics by processing temperature distribution data from the temperature converter, energy beam deciding means for deciding the output and moving velocity of the energy beam emitted to obtain desired hardening characteristics and according to hardening characteristics to be presumed, and energy beam control means for controlling at least one of the output and moving velocity of the energy beam according to the output of the energy beam deciding means to thus suppress the irregularities in the hardening characteristics, thereby obtaining hardening characteristics of the hardened material as desired even if pretreating conditions and beam output of the material to be hardened are varied.
