摘要	Effects of electromagnetical stirring on the structure and mechanical properties of pulse metal inert gas (MIG) weld metal for 2219 Al-Cu alloy were investigated. The results show that electromagnetical stirring decreases the thermal gradient at the solid-liquid interface in the weld pool and enhances the density of heterogeneous nucleation, results in the coarse and oriented columnar grains transforming into fine equiaxed grains; improves the morphology and distribution of alpha(Al)CuAl2 eutectic along grain boundaries; homogenizes Cu element and enhances the density of GP zone in weld metal, which accelerates the heterogeneous nucleation of theta' precipitates. Elctromagnetical stirring makes the ultimate tensile strength of weld joint enhance from 296.4 MPa to 326.0 MPa, the joint strength coefficient from 63% to 70% and ductibility from 4.7% to 7.6%.
