Dissimilar metal weld ECT testing Nickel-Alloy steel welding PWR RV SCC SG
Eddy Current testing (ECT) for detecting stress corrosion cracks (SCCs) in the vessel's dissimilar metal weld of PWR plants was carried out. Appropriate ECT with a single cross-coil can detect shallow artificial SCCs with depth of 0.5mm or over. And magnetic saturation method is very effective for decreasing noise signals come from permeability change in the boundary region between overlay and buttering of safe-end....
