Fourteen narrow-groove joints were welded on 0.91-m (36-in.) diameter AISI 316 stainless steel pipe. These joints were made by the automatic GTAW process, employing an Astro-Arc orbiting welding head and a 300-ampere, four-level, pulsed-arc power supply. Three different types of welding wire, ER 308, ER 316, and 16-8-2, were used. End preparations were made using a Crutcher Resources Corporation (CRC) pipe-facing machine. CRC's internal and external line-up clamps were employed for alignment and clamping. Longitudinal and radial shrinkage and ferrite measurements were taken on each weld.
