摘　　要：采用高铝粉煤灰、Si O2、B2O3、Ti和La2O3为原料,在约束条件下利用均匀设计法进行Q235钢A-TIG焊活性剂配方设计,大大减少了实验次数。复合活性剂最优配方:60%高铝粉煤灰、15.76%Si O2、8.88%B2O3、15.36%Ti和5%La2O3,焊缝深宽比为0.7503,约为无活性剂焊接时的4.3倍。Using high alumina fly ash, SiO2, B2O3, Ti and La2O3 as main materials, the uniform design method were employed to develop A-TIG activating fluxes of Q235 steel under the restricted conditions, and the testing times was remarkably decreased. In the optimum formula of composite activating flux, the mass percent of high alumina fly ash, SiO2, B2O3, Ti and La2O3 was 60%, 13.68%, 25.44%, 0.88% and 5% respectively. The depth-towidth ratio of weld joint reached 0.7503 and was controlled by 4.3 times compared without activating fluxes.
