Precision Forming Technology for Crimping of Large Straight Welded Pipes

Crimping plays a pivotal role in the production of large-diameter submerged-arc welded pipes. In the crimping forming process, predicting the springback while considering the real-time variation of material parameters is a major challenge faced by many researchers, which has a direct impact on the quality of the welded pipe. To address this problem, the precision forming technology of crimping was developed. The engineering theory of plastic...
