Abstract
In order to study the residual stress and evolution of 10mm thickness Q1100E ultra-high strength steel plate in butt welding.The finite element simulation software was used to simulate the change rule of welding residual stress,and the change trend of welding residual stress of Q1100E steel plate was combined with the welding form of butt joint by GMAW method to verify the simulation results.The two means verified each other to obtain reliable residual stress distribution of welded joints.The results show that during multi-pass welding,the weld seam underwent multiple welding thermal cycles;the weld center of each pass was greatly influenced by heat source.With temperature cooling fast,the weld shrank sharply,substantial residual stress varied greatly,and partial position could reach yield strength.Far away from the weld seam,it was less affected by heat source,and the residual stress was relatively smaller.关键词
