摘要
Abstract
By using large-scale general finite element analysis software ABAQUS, the finite element calculation model of spiral welded pipe two-wire submerged arc welding temperature field was built. The inside and outside welding process of spiral welded pipe two-wire submerged arc welding was simulated based on welding subroutine DFLUX which was compiled by FORTRAN language, combined with the element of birth and death technology in three-dimensional finite element method. It also realized finite element calculation under moving heat source load, and obtained temperature fields distribution in welding process, after cooling down, and in the full pipe body. The results indicated that during welding process, the temperature gradient near weld is large;it is tend to smooth transition far away from the weld. With welding heat source moving, the temperature center also move, the highest temperature can reach the melting point of base metal. Through the experiment, it is consistent with simulation results.关键词
