摘要
Using double eUipsoid heat source as inner heat source, a model of T-joint weldment of CLAW steel was established in order to analysis the temperature field, residual stress distribution and the angular deformation. And the temperature- dependent properties of material were considered in this model. The results show that the temperature distribution changes with the movement of heat source, every node goes through two thermal cycles. And every curve has two peak values ; the first peak value is higher than the second one. The largest deformation appears at the weld toe.
