摘　　要：针对某重工企业出现的动臂焊接缺陷率高的问题,运用6σ方法的DMAIC模型进行改进,并借助数理统计软件Minitab,经过正交试验设计法,确定焊接最佳参数组合,提出了一套具体的质量改进方案。结果表明,通过实施6σ方法提高了动臂焊接的过程能力、降低了动臂焊接缺陷率、提高了顾客满意度。6σ DMAIC model is applied to improve the high welding defects in a heavy industry, and the quality data was analyzed by Minitab software. Through orthogonal experimental design method to determine the optimal parameter combination of welding and proposed a set of specific quality improvement program. The results show that by implementing the process of 6σ method improves the ability of the welding boom, lower boom welding defect rate and improve customer satisfaction.
