Hybrid Laser/GMAW of High Strength Steel Gas Transmission Pipelines

项目名称：	Hybrid Laser/GMAW of High Strength Steel Gas Transmission Pipelines
摘要：	The project aims to develop innovative hybrid Yb-Fiber Laser and GMAW process and technologies for pipeline girth welding and to demonstrate the system under field conditions. ID root pass welding with GMAW will be the baseline with external hybrid root pass welding techniques developed for variations of laser power and root face thickness since this combination has the greatest potential to meet existing pipeline integrity requirements and facilitate the use of new and existing Yb-Fiber Laser GMAW hot and fill pass techniques. Advanced automation will be used to improve and develop root and fill pass processes, and for attainment of mechanical property requirements. In a consortium project offered for match requirements via a Group Sponsor Project (GSP) that is about to start at Edison Welding Institute (EWI), an integrated LBW/GMAW system based on a commercial bug and track system will be built, and will be used in this project to develop hybrid LBW/GMAW parameters for girth welds in X100 pipe.
