Abstract
THE OVERALL OBJECTIVE OF THE PROPOSED RESEARCH IS TO INVESTIGATE THE USE OF THE ELECTRICAL POTENTIAL DROP TECHNIQUE AS AN ACCELERATED TEST METHOD FOR DETERMINING THE STRESS CORROSION CRACKING RESISTANCE OF HY-130 STEEL WELDMENTS UNDER CATHODIC PROTECTION IN NATURAL SEAWATER AT AMBIENT TEMPERATURES. WELDS WILL BE DEPOSITED IN 1-INCH THICK HY-130 STEEL BUTT JOINTS. COMPACT TENSION FRACTURE-MECHANICS TYPE SPECIMENS WILL BE MACHINED FROM THE WELDS. DUPLICATE SPECIMENS WILL BE TESTED WITH THE FATIGUE CRACK LOCATED IN THE BASE METAL, IN THE HEAT-AFFECTED ZONE (HAZ), AND IN THE WELD METAL. THE RESULTS WILL BE COMPARED TO EXISTING DATA FROM LONG-TERM TESTS.
