    • PURPOSE: A welding process quality management method is provided to guarantee the welding process quality, thereby guaranteeing the quality of the power plant. CONSTITUTION: When the task for welding basic material alignment is good, a welding process quality management system(100) delivers a task order to preheat and weld to a welding terminal(400). When the task for preheating and the welding is good, the system determines whether or not the heat processing is necessary after the welding. When the task for the heat processing is good, the system delivers a task order for a non-destructive test to a non-destructive task terminal. When a defect for the non-destructive test is nonexistent, the system determines whether or not the residual stress measurement is necessary. When a residual stress measurement result is good, the system completes a welding task.

    • PURPOSE: A device for measuring a strain of a rotor bolt is provided to compare and measure a result value by attaching a strain gauge capable of measuring minute strain on an identical testing object, thereby enhancing the reliability of a test result. CONSTITUTION: A device for measuring a strain of a rotor bolt comprises an upper fixing plate(140), a lower fixing plate(170), a hydraulic linkage(160), a load cell(150), a strain gauge(200), and a data analyzing system(300). The upper and lower fixing plates fix both end portions of each of first and second rotor bolts. The hydraulic linkage applies hydraulic pressure to the upper and lower fixing plates, thereby applying the hydraulic pressure to the first and second rotor bolts. The load cell is arranged in the upper part of the hydraulic linkage, thereby regulating stress applied through the hydraulic linkage. The strain gauge measures contracting forces and expanding forces of each of the first and second rotor bolts. The data analyzing system is connected to the strain gauge, thereby collecting and analyzing first and second measurement data measured by relatively corresponding to the first and second rotor bolts.
