Electroplating repair machine for tack expansion and seal welding region, electroplating repair system, and operating method

An electroplating repair system, for repairing an expanded part and a sealing welding part through electroplating, the system comprising:

• an electroplating repair apparatus having a probe body extending a predefined length in a structure corresponding to an inner diameter part of a tube, an electroplating electrode attached to and surrounding an outer circumferential surface of the probe body, the electroplating electrode having a flange at one bottom end thereof, a sealing member attached to opposite end sides of the probe body to seal a target portion to be electroplated, wherein one of the sealing members engages the flange to seal the target portion, and a solution supply line supplying a solution to the target portion through the inside of the probe body;
• a manipulator having an extension arm extending a predefined length to change a position of the electroplating repair apparatus while holding the electroplating repair apparatus on one end side thereof, the extension arm coupled to and being driven by the manipulator wherein the extension arm has a structure surrounding an outer circumferential surface of the main body such that the extension arm is rotatable along the outer circumferential surface of the main body and wherein the extension arm has one or more tilting parts to change a tilting angle of the extension arm so as to change a position of the electroplating repair apparatus attached to one end side of the extension arm;
• a manipulator control unit controlling an operation of the manipulator, wherein the extension arm is driven with a control signal from the manipulator control unit;
• an electroplating control unit controlling operations of the electroplating electrode and the solution supply line of the electroplating repair apparatus;
• and
• a central control unit controlling operations of the electroplating control unit and the manipulator control unit.
