CLP WELDING DEVICE FOR REPLACING CONTAINMENT LINER PLATE AND REPAIRING METHOD USING THE SAME

摘要

The present invention relates to a welding apparatus for replacing a nuclear power CLP and a repair method using the same, and more particularly, to a welding apparatus for repairing a thinned portion by corrosion, comprising: a base portion having a rail- A driving unit connected to a lower side of the driving control unit and having a predetermined width so as to be inserted into a gap where a non-exposed region is formed, and a driving unit for driving the driving unit, And a welding portion provided at one end of the arm portion to allow the non-exposed portion to be thinned in the gap to be replaced by welding, thereby minimizing unnecessary removal of concrete and reinforcing bars in the liner plate repair work for unexposed corrosion defective portions, Can be repaired within CLP to ensure compatibility with And a nuclear CLP replacement welding device capable of permanently repairing all the corrosion defects of the CLP by repairing the corrosion defects on the back surface of the CLP located in the gap with the concrete slab or wall which is difficult for the operator to access inside will be.
