摘要：

Welded pipe is a tubular product made out of flat plates, known as skelp, that are formed, bent and prepared for welding. The most popular process for large diameter pipe uses a longitudinal seam weld. This paper focuses on experiments conducted on API-5L X70 steel welded using submerged arc welding procedure and multiarc technology. The authors chose to simulate also the process, using finite element analysis, in order to predict the temperature in the plates. Experimental results regarding the changes in the welding joints are presented at the end of contribution. The proposed FEA model for temperature prediction will be as input data for future stress and strains analysis.
