摘　　要：优化C-276合金脉冲电流自动化钨极气体保护电弧焊参数有着重要的意义。采用田口方法,设计了拥有4个焊接参数(脉冲电流、基值电流、脉冲电流占空比和脉冲频率),3个水平等级,9组实验方案的正交实验,利用方差分析每个焊接参数的贡献百分比。实验结果表明,当脉冲电流、基值电流、脉冲电流占空比和脉冲频率分别为165 A、77 A、60%和5 Hz时,焊件具有最大的熔深。It＇s significant to study optimizing C-276 alloy pulsed current gas tungsten arc welding parameters.In this paper,using the Taguchi method,designed with 4 welding parameters（pulse current,base current,pulse duty ratio and pulse frequency）,3 levels,orthogonal experiment with 9 groups of experimental program,the percentage contribution of each welding parameters using variance analysis.The experimental results showed that,when the pulse current,base current,pulse duty ratio and pulse frequency were 165 A,77 A,60% and 5 Hz,with the maximum penetration welding.
