摘　　要：结合精密焊接结构件(precision welding structure,PWS)工艺质量规划的实际需要,分析了PWS焊接形位精度质量变异的三方面属性,提出了以"质量变异系数"建立各质量因素与质量特征之间的对应关系,对专家经验和历史数据等定性模糊语言的定量表征方法;研究了PWS焊接质量因素综合分析模型,尝试对PWS焊接质量影响因素进行定量分析和决策。通过在典型PWS产品液力变矩器(HTC)的具体应用实例,阐述了焊接形位精度质量控制的策略,为PWS的焊接质量分析和工艺规划提供理论依据。Based on fussy set theory, a quantitative method for welding geometrical quality control of precision welding structure (PWS) is presented. The 'Quality Differentiation Coefficient' which characterizes the relation between quality difference and effective quality essentials is adopted to formulate the qualitative linguistic variables of welding quality difference properties. The welding quality analysis model which could fully utilize experts experiments and historical data for PWS is established to quantificational analysis and decision-making.
