摘要
Abstract
Aim at impact toughness of submerged arc welded pipe welding joints, it predicted HAZ structure of submerged arc welding through CCT chart and temperature field,determined HAZ mechanical property combined with microhardness,established entity model in impact test by using finite element dynamic analysis software ANSYS/LS -DYNA,and carried out numerical simulation for dynamic impact procedure of welding joints. The absorbed energies which groove located in weld,HAZ and base metal were calculated separately. It also analyzed the variation of impaet toughness.关键词
