Dept. of Transportation. Pipeline and Hazardous Materials Safety AdministrationUS Transportation CollectionThis investigation is part of a major consolidated program of research sponsored by the US Department of Transportation (DOT) Pipeline Hazardous Materials Safety Administration (PHMSA) and the Pipeline Research Council International (PRCI) to advance weld design, establish weld testing procedures, improve assessment methodologies, and develop optimized welding solutions for joining high strength steel pipe. This project focused specifically on development of optimized welding solutions for X100 line pipe steel. It was undertaken in direct response to growing industry demand for greater predictability in overall weld performance and mechanical properties. In general, the more exacting requirements imposed by strain based design are driving industry demand for improved performance as indicated by two PHMSA sponsored government industry forums - the first on pipeline research and development in March 2005 and the second on welding research in January 2006
