DU Chang-qing

Abstract

At present,CRC automatic welding equipment is the most advanced pipeline welding equipment in the world which has the features of high automation level,fast welding speed and all-weather operational capability.After comprehensive assessment,it was decided to adopt CRC automatic welding process for pipeline welding in the plain area of Kazakstan B section of Central Asia Natural Gas Pipeline.The pipeline welding work was successfully fulfilled both in quality and in quantity.In this paper,the similar welding technologies at home and abroad are compared,and the characteristics of CRC welding process,its applications and economic benefits are introduced.
