Open root welds on pipe used in the Alberta Oil Sands Projects arc being made faster and with dewwe defects than with traditional welding methods by using the Surface Tension Transfer (STT) process For the World Class Millennium Project on the Suncor oil sands site in Fort McMurray, Alberta, the process is being used to weld root passes as well as complete welds in both carbon steel and stainless steel pipe, including pipe with up to 9 chrome. On many of these projects, the process is also being integrated into a new automatic orbital pipe welding system, AutoWeld, which provides even faster production.
