Abstract
Research carried out in this project dealt with all position GMA welds in HY80 plates. Flat, horizontal, overhead and vertical down welds were prepared. Three wire compositions were employed, L-95 and L-120 by Linde and LA100 by Lincoln. Plates machined to double V 50 degrees compound angle were welded in a rugged weld fixture at 26 - 28 V, 200 - 240 A in 14 - 18 passes depending on position. Metallography, NDT and microhardness tests were performed to characterize the weld material. Weld structure was homogenous with good hardness values.
