Numerical simulation for casting process may optimize craft design, shorting trial cycle, cut the cost, decrease casting defect and assure the casting quality.
铸造过程的数值模拟可以优化工艺设计，缩短产品试制周期，降低成本，减少铸件缺陷，确保铸件质量。
The results show that the partial unmelted region, casting defect structure and secondary crack form in the welding seam, which result in the low stress breakage of the samples.
结果表明：在焊缝区域内存在着局部未熔区以及铸造疏松组织和二次裂纹等缺陷，这是导致试样低应力断裂的根本原因。
