摘　　要：通过对比正交设计法介绍了均匀设计法的优点,引入铜及铜合金手工自蔓延焊接快速评价方法,并采用均匀设计法优化已有铜基燃烧型焊条配方。选择高热剂Al+CuO、造渣剂B2O3、合金剂Ni、合金剂Zn含量为影响因素,以燃速、热量、飞溅、黏度、脱渣、流动、铺展、气孔、夹杂、强度这十项性能作为主要考察指标,按照均匀设计法流程,经计算配方优化结果为:高热剂含量为75、B2O3含量为23、Ni含量为1、Zn含量为1,并对调整配方后的最终焊缝成型情况进行了机理解释。which is based on self-propagating high-temperature synthesis（SHS） theory and manual arc welding technique of copper and copper alloy.It was introduced that principle of uniform design in contrast with orthogonal design and fast assessment standard of copper and copper alloy＇s Manual SHS welding technology,on which a project for formula optimization of SHS welding rod is presented.Thermite Al＋CuO,slagforming constituent B2O3 and alloying constituent Ni,Zn were chosen as the influencing factors.The main survey index comprises combustion speed,heat quantity,spatter,viscosity,slag detachability,fluidity,spreading,gas hole, inclusion,intensity.The final result of formula optimization shows that it will be welded better when content of thermite was 75, slagforming constituent B2O3 was 23,alloying constituent Ni as well as Zn was 1.Final appearance of the weld seam was analyzed when the formula was adjusted.
