Abstract:

A comprehensive comparison between electroslag surfacing ESS and submerged arc surfacing SAS using 30 mm 1.2 inch wide x 0.5 mm 0.020 inch thick Ni Alloy 625 strip was conducted in both the as-deposited and stress relieved at 604OC, 1120OF conditions. In most cases, exactly duplicate cladding conditions were used to best compare ESS with SAS. Ni Alloy 625 strip was deposited on 10 cm 4 inch thick flat plates and 64 cm 25 inch diameter shafting both MIL-S-23284 Class 1 steel using optimized ESS and SAS processes. Tensile, CVN toughness, and face and side bend tests were performed on as-welded and stress relieved cladding at room temperature. Microstructural analyses of the clad specimens were performed using optical and electron microscopy.
