| Abstract: | During gas field construction, especially for natural gas processing plant, gas gathering station and gas gath- ering branch line, the weldability of dissimilar steel pipe and weld quality become worse because of dissimilarity of chemical composition, physical properties, and metallurgical composition. In addition, it is stricter to adopt welding process and welding materials. In order to meet specified design requirements, through analysis on weldability of dissimilar steel pipe, it summarized welding process from several aspects, such as choosing welding method, material;parameter, and groove type. It presented welding process and operation point, taking an example from welding case of dissimilar steel pipe in recent year construction. |
