Alternative methods for C.R.A pipeline welding

Book ·
OSTI ID:400956
The application of the GTAW process for C.R.A. (Corrosion Resistant Alloy) linepipe welding is a well known practice, nevertheless the high construction costs associated to the use of this process particularly for root pass welding (low welding speed) necessitate consideration of an updated version of the GMAW process (higher welding speed) for the same application. The present paper describes the progress obtained in using alternative welding methods to GTAW Cold wire such as: GTAW hot wire and GMAW to increase the welding speed and consequently reduce the overall project cost. The authors feel that this approach is essential to increase the pipelaying productivity of a C.R.A. linepipe materials, at present still too far from that of the Carbon steel one.
