    • 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: An eddy current probe for surface inspection and an eddy current inspection device therewith are provided to prevent harmful materials and contaminants and to simplify an inspection procedure. CONSTITUTION: An eddy current probe(10) for surface inspection comprises a main body(12), a contact part(14), an eddy current sensor(16), a pressing part(24), a first elastic member, a rod(34), and a second elastic member. The contact part is coupled to the main body and has convex parts(14a) and concave parts(14b). The eddy current sensor is coupled to the ends of the convex parts of the contact part. The pressing part presses the top of a dovetail joint. The first elastic member is inserted between the pressing part and the main body and supplies elastic force to the pressing part. One end of the rod is hinged on the contact part, and the other end has a saw-toothed part corresponding to the hook of the dovetail joint. The second elastic member is inserted between the other end of the rod and the contact part.
    • 目的:提供一种用于表面检测的涡流探头和一个涡流检测装置,以防止有害物质和污染物,并简化检查程序。 构成:用于表面检查的涡流探针(10)包括主体(12),接触部分(14),涡流传感器(16),按压部分(24),第一弹性部件,杆( 34)和第二弹性构件。 接触部分连接到主体并具有凸部(14a)和凹部(14b)。 涡流传感器耦合到接触部分的凸部的端部。 按压部分按压燕尾接头的顶部。 第一弹性构件插入在按压部和主体之间,并且向按压部提供弹力。 杆的一端铰接在接触部上,另一端具有与燕尾接头的钩对应的锯齿部。 第二弹性构件插入杆的另一端和接触部之间。
