Brazing apparatus and method for anode target plate

A brazing apparatus for brazing an anode target plate of an X-ray generator, comprising:

• a vacuum part configured to provide, during brazing, a vacuum environment for (i) a target plate main body that is formed of an alloy, (ii) a brazing material, and (iii) a substrate to be brazed to a surface of the target plate main body;
• an induction brazing part configured to apply an induction current to the target plate main body, the brazing material, and the substrate within the vacuum part to heat the brazing material to a temperature that is higher than a melting point of the brazing material to cause the substrate to be brazed to the surface of the target plate main body via a melting of the brazing material and a resulting reaction;
• a directional energy welding part configured to perform heating by applying a directional energy beam to a location on the target plate main body having a temperature that is less than a predetermined temperature threshold;
• a sensor configured to measure a temperature of the target plate main body during brazing;
• and
• a controller configured to determine, based upon the measured temperature, the location on the target plate main body having the temperature less than the predetermined temperature threshold, and to control the directional energy welding part to cause the directional energy welding part to apply the generated directional energy beam to the location.
