Installation of new pipelines and therefore the welding related business as a part of the pipeline production process is a growing area. One reason is the increase use of combined cycle power generation plants that need natural gas as a fuel combined with the need for district heating networks. Many welding technologies such as laser welding, radial friction welding etc. have been tried to increase the productivity but still the mechanized gas metal arc welding process is a widely used pipe girth welding technique. The productivity of pipeline constructions depend on two different aspects of the welding process: On the one hand the root pass welding speed is the relevant parameter with respect to the pipeline construction speed and on the other hand the deposition rate of the welding process determines the number of welding stations needed for an optimized fill pass welding. Based on a customer case this paper describes how the use of modern GMAW processes lead to an improved productivity and a good welding quality. |
