摘要
通过孕育处理可扩大熔核凝固组织中的等轴晶区，并在合适的工艺条件下获得呈单一等轴晶组织的熔核。同时，对孕育处理前后的点焊接头力学性能作了系统的比较研究。
Equiaxial area in solidified nugget structure can be extended by incubating process,and the nugget with single equiaxial structure can be acquived under appropriate technologicalcondition.Meanwhile, systematic comparison of the mechanical properties of the spot weldingjoints before and after inacubating process was carried out.
