The objective of this research program was to investigate the girth welding of pipe in the vertical or near vertical position (2G) for J-welding construction in deep-water applications. The tasks investigated included two approaches (depositing the root pass on the pipe I.D. with the balance of welding on the O.D. and all welding on the O.D.), arc-welding processes, shielding gases, arc welding parameters, weld joint design, mechanical properties of deposited welds, and determination of the extent of heat buildup in the pipe during welding. Welding procedures were developed for both the internal root/balance O.D. welding and for the all external welding approaches.
